AB  - Recovering the bioactive components from pomegranate peel (PP) in the fruit-processing industry has attracted great attention in terms of minimizing the waste burden, as well as providing a new source of a multitude of functional compounds. The present study aimed to develop a feasible microencapsulation process of PP extract by using pectin and a pectin/2-hydroxypropyl-β-cyclodextrin (HP-β-CD) blend as coating materials. Microsized powders obtained by a spray drying technique were examined in terms of technological characteristics, exhibiting high powder yield and desirable moisture content, flowability, and cohesive properties. Assuming that the interactions with the used biopolymers occur on the surface hydrophobic domain, their presence significantly improved the thermal stability of the microencapsulated powders up to 200 °C. The health-promoting effects of PP have been associated with its high content in ellagitannins, particularly punicalagin. The obtained PP powders exhibited strong antioxidant and hypoglycemic potential, while an antimicrobial assay revealed their potent activity against Gram-positive bacteria. Additionally, an in vitro release study suggested that the used biopolymers can modify the release of target bioactive compounds, thus establishing a basis for developing an oral-controlled release system. Altogether, biowaste valorization from PP by the production of effective multifunctional microsized powders represents a sustainable way to obtain novel nutraceuticals and/or pharmaceuticals.

AB  - Inflammation and oxidative stress are common problems in biomaterial science. Therefore, antioxidative components, especially those of natural origin, can be of great value in improving biomaterial formulations for medical devices. It is already well known that the most notable exogenous antioxidants are ascorbic acid, polyphenolic compounds, and minerals such as selenium and zinc. In our research, we prepared a composite based on polyphenolic resveratrol nanobelts and selenium nanoparticles and explored its’ antioxidative potential.

AB  - Since LiFePO4 batteries play a major role in the transition to safe, more affordable and sustainable energy production, numerous strategies have been applied to modify LFP cathode, with the aim of improving its electrochemistry. In this contribution, a highly vanadium-doped LiFe0.9V0.1PO4/C composite (LFP/C-10V) is synthesized using the glycine combustion method and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Thermogravimetry Differential Thermal Analysis (TGDTA) and Cyclic Voltammetry (CV). It is shown that 10wt.% of vanadium can substitute Fe positions, thus decreasing unit cell volume, which is followed by generation of Li3V2PO4 traces, as detected by CV. High vanadium doping does not change the carbon content in the composite (≈ 13 wt.%) but improves its electronic conductivity and electrochemical performance in both aqueous and organic electrolytes. The reversibility and current response are increasing following the trend: LFP/C, LFP/C -3mol%V, LFP/C - 5mol % and LFP/C-10 mol %. The best specific capacity is obtained for the most highly doped olivine, which exhibits a reversible process at 1 mV s-1 in an aqueous electrolyte, thus showing a peak-to-peak distance of 56 mV. The high capacity of LFPC-10V is measured in both LiNO3 and NaNO3 electrolytes amounting to around 100 mAh g-1 at 20 mV s-1. Still, the material is only stable in LiNO3 electrolyte, making it more suitable for Li than Na-ion aqueous rechargeable batteries.

AB  - Ceramic/polymer composites can be chemically stable, mechanically strong, and flexible, which make them candidates for electric devices, such as pressure or temperature sensors, energy storage or harvesting devices, actuators, and so forth. Depending on the application, various electrical properties are of importance. Polymers usually have low dielectric permittivity, but increased dielectric permittivity can be achieved by the addition of the ceramic fillers with high dielectric constant. With the aim to enhance dielectric properties of the composite without loss of flexibility, 5 wt% of BaTiO3-Fe2O3 powder was added into a polyvinylidene fluoride matrix. The powder was prepared by different synthesis conditions to produce core/shell structures. The effect of the phase composition and morphology of the BaTiO3-Fe2O3 core/shell filler on the structure and lattice dynamics of the polymer composites was investigated. Based on the results of the thermal analysis, various parameters of ceramic/polymer composites were determined. Differences in the phase composition and morphology of the filler have an influence on the formation of various polyvinylidene fluoride allomorphs and the degree of crystallinity. Furthermore, the dielectric performances of pure polyvinylidene fluoride and the polymer/ceramic composites were measured.

AB  - Goal: Clinical interpretation of an electrocardiogram (ECG) can be detrimentally affected by noise. Removal of the electromyographic (EMG) noise is particularly challenging due to its spectral overlap with the QRS complex. The existing EMG-denoising algorithms often distort signal morphology, thus obscuring diagnostically relevant information. Methods: Here, a new iterative regeneration method (IRM) for efficient EMG-noise suppression is proposed. The main hypothesis is that the temporary removal of the dominant ECG components enables extraction of the noise with the minimum alteration to the signal. The method is validated on SimEMG database of simultaneously recorded reference and noisy signals, MIT-BIH arrhythmia database and synthesized ECG signals, both with the noise from MIT Noise Stress Test Database. Results: IRM denoising and morphology-preserving performance is superior to the wavelet- and FIR-based benchmark methods. Conclusions : IRM is reliable, computationally non-intensive, fast and applicable to any number of ECG channels recorded by mobile or standard ECG devices.

AB  - While the effects of chronic exposure to microplastic particles (MPs) are extensively studied, the outcomes of a single treatment have received relatively less attention. To investigate MPs’ potential acute toxicity, including their impact on general health status (victual consumption, sensorimotor deficits, and clinical toxicity signs) and serum biochemical parameters (markers of organ/tissue function and oxidative stress indicators), we administered thoroughly characterized MPs (1.4, 35, or 125 mg/kg), generated from polyethylene terephthalate (PET) bottles, to adult male Wistar rats via oral gavage. The MPs’ short-term effects were assessed with well-established tests and methods. The results point to the absence of sensorimotor deficits and clinical toxicity signs, while levels of markers of liver, heart, and kidney function were altered in all MP groups. Decreased victual consumption and increased levels of oxidative stress indicators were evident following treatment with the two higher MP doses. Presented data indicate that examined MPs are able to initiate the development of local changes in tissues and organs within a short time frame, potentially leading to their damage and dysfunction. This study may increase the awareness of the detrimental effects of plastic contamination, as even a single exposure to MPs may provoke adverse health outcomes.

abstract = "While the effects of chronic exposure to microplastic particles (MPs) are extensively studied, the outcomes of a single treatment have received relatively less attention. To investigate MPs’ potential acute toxicity, including their impact on general health status (victual consumption, sensorimotor deficits, and clinical toxicity signs) and serum biochemical parameters (markers of organ/tissue function and oxidative stress indicators), we administered thoroughly characterized MPs (1.4, 35, or 125 mg/kg), generated from polyethylene terephthalate (PET) bottles, to adult male Wistar rats via oral gavage. The MPs’ short-term effects were assessed with well-established tests and methods. The results point to the absence of sensorimotor deficits and clinical toxicity signs, while levels of markers of liver, heart, and kidney function were altered in all MP groups. Decreased victual consumption and increased levels of oxidative stress indicators were evident following treatment with the two higher MP doses. Presented data indicate that examined MPs are able to initiate the development of local changes in tissues and organs within a short time frame, potentially leading to their damage and dysfunction. This study may increase the awareness of the detrimental effects of plastic contamination, as even a single exposure to MPs may provoke adverse health outcomes.",

AB  - Hydroxyapatite (HAp) has been the main protagonist in the quest for an ideal biomaterial for regenerative medicine over the last half a century. To control its properties, this material has commonly been doped with chemical elements other than its natural stoichiometric constituents: Ca, O, P, and H. Here, we report on the first analysis of the biological response to germanium-doped hydroxyapatite (Ge-HAp). Cytotoxicity, osteogenic differentiation induction, and colony formation potential were measured on dental pulp stem cells, while the antimicrobial effect was assessed against Gram-negative Escherichia coli, Gram-positive methicillin-resistant Staphylococcus aureus (MRSA), and Candida albicans. All analyses were run in comparison to Ge-free HAp. Cell viability was inversely dependent on the nanoparticle concentration and incubation time. Adding Ge to HAp reduced cell viability relative to HAp after 24–72 h incubation periods, but the effect was reversed after longer incubations, when the viability of cells treated with low doses of Ge-HAp exceeded that of HAp-treated cells and became comparable with control culture. Both HAp and Ge-HAp induced mineral formation in the cell culture, but the effect was more pronounced for Ge-HAp. Likewise, relative to both control cells and cells exposed to HAp, Ge-HAp upregulated the expression of all three osteogenic markers analyzed, namely, alkaline phosphatase, RUNX2, and osteocalcin, exerting the key influence on osteogenesis in its early, differentiation stage. The colony formation capacity of stem cells, however, was impaired by HAp and even more so by Ge-HAp. The antimicrobial effect was dependent on the microorganisms tested. Thus, whereas the antimicrobial activity was absent against E. coli, it was evident against MRSA and C. albicans. While the antibacterial activity against MRSA was weakened by the addition of Ge to HAp, the antimycotic activity against C. albicans was intensified with the addition of Ge. These findings demonstrate a significant potential of Ge-doped HAp nanoparticles in regenerative medicine due to their pronounced biocompatibility, osteoinductivity, and antimicrobial activity.

AB  - Ceramic/polymer composites can be chemically stable, mechanically strong, and flexible, which make them candidates for electric devices, such as pressure or temperature sensors, energy storage or harvesting devices, actuators, and so forth. Depending on the application, various electrical properties are of importance. Polymers usually have low dielectric permittivity, but increased dielectric permittivity can be achieved by the addition of the ceramic fillers with high dielectric constant. With the aim to enhance dielectric properties of the composite without loss of flexibility, 5 wt% of BaTiO3-Fe2O3 powder was added into a polyvinylidene fluoride matrix. The powder was prepared by different synthesis conditions to produce core/shell structures. The effect of the phase composition and morphology of the BaTiO3-Fe2O3 core/shell filler on the structure and lattice dynamics of the polymer composites was investigated. Based on the results of the thermal analysis, various parameters of ceramic/polymer composites were determined. Differences in the phase composition and morphology of the filler have an influence on the formation of various polyvinylidene fluoride allomorphs and the degree of crystallinity. Furthermore, the dielectric performances of pure polyvinylidene fluoride and the polymer/ceramic composites were measured.

AB  - This paper presents two classes of integer codes that are suitable for use in local area networks. The first class of codes can correct h-bit burst errors within one b-bit byte and detect l-bit burst errors within one b-bit byte (1 ≤ h < l < b), while the second class of codes, in addition to correcting/detecting the mentioned types of errors, can also detect d-bit burst errors within two b-bit bytes (1 ≤ d < b). Both classes of codes are defined over integer rings and are generated by computer search. To evaluate the performance of both classes of codes, we analyze their probabilities of incorrect decoding for binary symmetric and bursty channel.

AB  - Magnesium titanate ceramics were prepared by reactive spark plasma sintering (SPS) at 1200 °C for 5 min. Prior to sintering, MgO and TiO2 powders were mixed by high energy ball milling (HEBM) for 15, 30, or 60 min. The effect of milling time on phase composition was analyzed by X-ray diffraction (XRD) for milled powders and sintered specimens. The morphology of the sintered ceramics was investigated by scanning electron microscopy (SEM), while elemental distribution was determined by energy dispersive spectroscopy (EDS). The presence of the MgTi2O5 phase was detected in XRD and was confirmed by EDS analysis. Microcracking was observed for specimens prepared with longer milling times and attributed to the coefficient of thermal expansion (CTE) mismatch dominantly due to the anisotropic crystal structure of MgTiO3 phase. The sample milled for 15 min showed the highest Vickers hardness due to less or no microcracking and nearly full density. The dielectric measurements in the range of 10 Hz–250 MHz demonstrated extremely high dielectric permittivity, as high as 104 at 1 kHz. An increase in loss tangents was observed due to oxygen vacancy formation, which was promoted by the vacuum environment during SPS. Oxygen vacancy-related dielectric relaxation was also detected and explained.

AB  - Advancements in computer capabilities enable predicting process outcomes that earlier could only be assessed after post-process analyses. In aerospace and automotive industries it is important to predict parts properties before their formation from liquid alloys. In this work, the logistic function was used to predict the evaporation rates of the most detrimental impurities, if the temperature of the liquid aluminum alloy was known. Then, parameters of the logistic function were used to determine the transition points where the reaction order was changing. Samples were heated to 610 °C, 660 °C, 710 °C, and 760 °C for one hour, after which the chemical analyses were performed and evaporation rates were calculated for Cd, Hg, Pb and Zn elements. The pressure inside the encapsulated area was maintained at 0.97 kPa. Whereas parameters that define the evaporation rate increase with the temperature increase, the maximum evaporation rates were deduced from the experimental data and fitted into the logistic function. The elemental evaporation in liquid-aluminum alloys is the best defined by the logistic function, since transitions from the first to zero-order-governed evaporation reactions have nonsymmetrical evaporation rate slopes between the lowest and the highest evaporation rate point.

abstract = "Advancements in computer capabilities enable predicting process outcomes that earlier could only be assessed after post-process analyses. In aerospace and automotive industries it is important to predict parts properties before their formation from liquid alloys. In this work, the logistic function was used to predict the evaporation rates of the most detrimental impurities, if the temperature of the liquid aluminum alloy was known. Then, parameters of the logistic function were used to determine the transition points where the reaction order was changing. Samples were heated to 610 °C, 660 °C, 710 °C, and 760 °C for one hour, after which the chemical analyses were performed and evaporation rates were calculated for Cd, Hg, Pb and Zn elements. The pressure inside the encapsulated area was maintained at 0.97 kPa. Whereas parameters that define the evaporation rate increase with the temperature increase, the maximum evaporation rates were deduced from the experimental data and fitted into the logistic function. The elemental evaporation in liquid-aluminum alloys is the best defined by the logistic function, since transitions from the first to zero-order-governed evaporation reactions have nonsymmetrical evaporation rate slopes between the lowest and the highest evaporation rate point.",

AB  - Four samples containing magnetic iron oxide nanoparticles (MIONs) of various sizes are prepared employing a simple low-temperature method of oxidative precipitation from FeCl2∙4H2O-NaOH-NaNO3 aqueous solution. For the preparation of two samples, the usual oxidation-precipitation synthesis protocol is modified by using ethylenediaminetetraacetic acid (EDTA) chelating agent as a stabilizer of the Fe2+ ions in a solution, which results in the partial capping of the prepared MIONs with EDTA molecules. Three out of four samples are subjected to citric acid (CA) functionalization in the post synthesis protocol. Structural and magnetic properties of the synthesized MIONs are assessed using various experimental techniques (XRD, TEM, Fourier transform infrared, dynamic light scattering, Mössbauer, and SQUID). The average size of spherical-like MIONs is tuned from 7 nm to 38 nm by changing the synthesis protocol. Their room temperature saturation magnetization, M s, is in the range of 43 to 91 emu g−1. Magnetic heating ability, expressed via specific absorption rate value, which ranges from 139 to 390 W/gFe, is discussed in relation to their structural and magnetic properties and the possible energy dissipation mechanisms involved. The best heating performance is exhibited by the sample decorated with EDTA and with a bimodal size distribution with average particle sizes of 14 and 37 nm and M s = 87 emu g−1. Though this sample contains particles prone to form aggregates, capping with EDTA provides good colloidal stability of this sample, thus preserving the magnetic heating ability. It is demonstrated that two samples, consisting of 7 nm-sized CA- or 14 nm-sized EDTA/CA-functionalized superparamagnetic MIONs, with a similar hydrodynamic radius, heat in a very similar way in the relatively fast oscillating alternating current magnetic field, f = 577 kHz.

AB  - Y0.8−xGdxF3:Yb/Er mesocrystals with a biocompatible surface and diverse morphological characteristics were successfully synthesized using chitosan-assisted solvothermal processing. Their structural properties, studied using X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning and transmission electron microscopy and energy dispersive X-ray analysis, were further correlated with the up-conversion emission (λexc = 976 nm) recorded in function of temperature. Based on the change in the visible green emissions originating from the thermally coupled 2H11/2 and 4S3/2 levels of Er3+, the corresponding LIR was acquired in the physiologically relevant range of temperatures (25–50 °C). The detected absolute sensitivity of about 0.0042 °C−1, along with the low cytotoxicity toward both normal human lung fibroblasts (MRC-5) and cancerous lung epithelial (A549) cells, indicate a potential for use in temperature sensing in biomedicine. Additionally, their enhanced internalization in cells, without suppression of cell viability, enabled in vitro labeling of cancer and healthy cells upon 976 nm laser irradiation.

AB  - Today, rechargeable Li- ion batteries have widespread use as power sources. However, the organic electrolytes used in these batteries are toxic, so the use of aqueous electrolytes is preferred. Vanadium pentoxide has been intensively studied as a cathode material for use in batteries with aqueous electrolytes. In this work, the V2O5 composite with reduced graphene oxide was synthesized by a simple sol-gel synthesis. Material was characterized by XRD, thermal analysis and optical microscope. The electrochemical properties of the composite material were examined by the method of cyclic voltammetry at different polarization speeds. Aqueous electrolytes LiNO3, NaNO3 and Mg (NO3)2 were used. These characteristics were correlated to determine for which type of batteries the tested composite can be used, as well as how reduced graphene oxide affects the stability and capacity value of V2O5.

AB  - Nanotechnology, as a most promising approach in material science, has resulted in numerous enhancements and breakthroughs in diverse scientific fields. One of the examples is selenium nanoparticles (SeNPs) which emerged as a new form with some improved properties compared to other Se forms. Among these properties, anticancer, antimicrobial, antioxidative, and reduced toxicity are the most interesting from the aspect of biomedical applications. Due to simplicity, short duration, scalability, and reproducibility, chemical reduction is a synthesis technique very often applied in SeNPs production. The choice of reducing agents, their molar ratio with a precursor, and the choice of stabilizing agents are recognized as determining parameters for the application efficiency of designed SeNPs.
This presentation includes an overview of the results of SeNPs obtained by the reduction of sodium selenite and stabilized with different agents. Furthermore, the effects of synthesis parameters on the properties of obtained particles (size, morphology, crystallinity, stability, surface chemistry) and biological activities such as antimicrobial, antioxidative, and cytotoxicity will be elaborate. In addition, some potential applications of SeNPs will be discussed, with particular reference to the results of in vivo experiments.

AB  - The aim of the research was to develop microencapsulated powders of bilberry and chokeberry extracts via the spray drying technique. Two biopolymers, pectin alone and in combination with HP-β-CD, were used to preserve the antioxidant, hypoglycemic, photoprotective, and antimicrobial bioactivity of the berry leaf extracts. Moreover, the formed powders were characterized in terms of technological, chemical, and several biological properties. The obtained micro-sized powders (mean average particle diameter from 3.83 to 5.94 µm) demonstrated a process yield of up to 73%. The added biopolymers improved the flowability and cohesive properties of the powders and increased their thermal stability to 170 °C. The total content of polyphenolics in the powders ranged from 323.35 to 367.76 mg GAE/g DW for bilberry and from 186.85 to 227.59 mg GAE/g DW for chokeberry powders; meanwhile, chlorogenic acid was the predominant compound in powders. All samples showed stronger α-glucosidase inhibitory activity (IC50 values ranged from 5.00 to 19.59 µg/mL) compared with the reference standard. The study confirmed that spray drying is a suitable method for the preservation of the polyphenolic-rich extracts, while the addition of carriers has a positive effect on the improvement of microencapsulated powders’ properties.

abstract = "The aim of the research was to develop microencapsulated powders of bilberry and chokeberry extracts via the spray drying technique. Two biopolymers, pectin alone and in combination with HP-β-CD, were used to preserve the antioxidant, hypoglycemic, photoprotective, and antimicrobial bioactivity of the berry leaf extracts. Moreover, the formed powders were characterized in terms of technological, chemical, and several biological properties. The obtained micro-sized powders (mean average particle diameter from 3.83 to 5.94 µm) demonstrated a process yield of up to 73%. The added biopolymers improved the flowability and cohesive properties of the powders and increased their thermal stability to 170 °C. The total content of polyphenolics in the powders ranged from 323.35 to 367.76 mg GAE/g DW for bilberry and from 186.85 to 227.59 mg GAE/g DW for chokeberry powders; meanwhile, chlorogenic acid was the predominant compound in powders. All samples showed stronger α-glucosidase inhibitory activity (IC50 values ranged from 5.00 to 19.59 µg/mL) compared with the reference standard. The study confirmed that spray drying is a suitable method for the preservation of the polyphenolic-rich extracts, while the addition of carriers has a positive effect on the improvement of microencapsulated powders’ properties.",

AB  - Phase transition from ZnTiO3 to Zn2TiO4 represents second order phase transition from perovskite (zinc metatitanate) with a hexagonal ilmenite structure (R¯3) to inverse spinel (zinc orthotitanate) cubic structure (Fd¯3m) stable from room temperature to its melting (liquid) was identified during sintering of ZnTiO3 nanopowder. Kinetic of the phase transition has been observed as dimensional changes using dilatometric device thermo-mechanical analyzer TMA SETARAM model SETSYS Evolution and as thermal changes with SETARAM SETSYS Evolution TGA-DTA/DSC device. Two forms of specimens were employed nanopowder and polycrystalline sintered bulk specimen. It was found that sintering process and relaxation of the nanodimensional powder particles stress phenomena strongly influence kinetic of the phase transition. Dilatometric results known from previous investigations are now compared with differential thermal analysis results.

AB  - The aim of this research was to investigate for the first-time photocatalytic degradation of methylene blue over SrGd2O4 powders co-doped with constant Er3+ (0.5 at.%) and different Yb3+ (1, 2.5 and 5 at.%) concentrations. Samples were successfully prepared via sol-gel assisted combustion method. They exhibit photoluminescence properties which are manifested as red emission at 661 nm (4F9/2 → 4I15/2) and two green emissions at 551 and 523 nm (4S3/2 → 4I15/2 and 2H11/2 → 4I15/2). X-ray Powder Diffraction pattern proved that all samples crystallize as a pure orthorhombic phase. Scanning electron microscopy was used for morphology characterization and it revealed the existence of porous agglomerated round-shaped particles. Energy dispersive X-ray spectroscopy showed the presence of dopant ions and even distribution of all constituting elements. To calculate the energy band gap, UV-VIS diffuse reflectance spectroscopy was performed and a value of 4.3 eV was obtained, as well as the four additional values from the bands at lower energies. Photocatalytic degradation of methylene blue was monitored using UV-VIS absorption spectroscopy. Obtained results were promising since after 4 h of exposure to the simulating Sun irradiation, more than 50% of the starting dye concentration was mineralized.

AB  - Mixed spinel ferrites MgxNi1-xFe2O4 were synthesized via sol-gel combustion synthesis with citric acid as fuel, followed by calcination at 700 °C for 3 hours. Obtained powders were characterized via X-ray diffraction analysis (XRD), X-ray photoelectron (XPS), FTIR and Raman spectroscopy and FESEM microscopy. Elemental composition was examined via energy dispersive spectroscopy (EDS). Humidity sensing properties were tested by measuring AC impedance in a climactic chamber at 25 °C and in the relative humidity range of 40–90%. Temperature sensing properties were tested by measuring DC resistance at 40% RH in the temperature range 40–90 °C. Synthesized powders were proven to be pure spinel Fd 3m phase with spherical, slightly agglomerated particles. Substitution of Mg with Ni results in structural changes such as a change in inversion parameter and particle agglomeration, which influences sensing properties of the material. Results show that the sensing properties of magnesium ferrite, which is already a well-established NTC sensor, can be improved by incorporating 10% of nickel in the spinel lattice structure. Mg0.9Ni0.1Fe2O4 exhibited higher temperature sensitivity and higher sensitivity towards humidity compared to MgFe2O4, while further substitution of Mg with Ni resulted in the decline of sensing properties, increase in particle size and agglomeration degree.

AB  - Photovoltaic silicon converts sunlight in 95% of the operational commercial solar cells and has the potential to become a leading material in harvesting energy from renewable sources, but silicon can hardly convert clean energy due to technologies required for its reduction from sand and further purification. The implementation of the novel materials into photovoltaic systems depends on their conversion efficiency limited by the material's inherent properties, longevity dependent on internal stability, and ease of manufacturing process. A major challenge is discovering a multilayered set of different photovoltaic materials capable of converting clean energy from a wider spectra range since emerging materials and technologies such as dye-sensitized and quantum dots suffer from low conversion efficiencies while perovskite and organic cells have short longevity in atmospheric conditions. Presently, improving technologies for commercialized materials and creating multijunction solar cells enhanced by new photovoltaic materials is a path toward cleaner energies. With the rapid development of the integrative technologies and challenges that photovoltaics for clean energy conversion are facing, the entire clean photovoltaic industry could arise by bottom-up course as a part of integrative technologies rather than erecting large power plants.

AB  - Kontinuirano interesovanje za nanočestice različitih materijala i njihove kompozite stvorilo je brojna pitanja u vezi njihove potencijalne toksičnosti. Polifenol resveratrol i jedinjenja sa selenom su među agensima čijoj je upotrebi nanotehnologija omogućila nov pristup. U formi nanočestica, oni pokazuju poboljšanu biokompatibilnost i biološke efekte, kao što je antimikrobna aktivnost. Na osnovu podataka iz literature, nanočestice selena su najčešće manje toksične nego jedinjenja sa selenom. U našem istraživanju, najpre smo pripremili kompozitni materijal na bazi selena i resveratrola. Nakon toga, kompozit i njegove komponente bili su testirani pomoću MTT tetrazolijumske boje za utvrđivanje citotoksičnosti, komet testom na genotoksičnost i nitroplavo-tetrazolijumskim testom za procenu nivoa superoksidnih anjona. U svim eksperimentima je korišćena zdrava ćelijska linija fibroblasta čoveka (MRC-5). Rezultati su pokazali da, iako čestice resveratrola ispoljavaju citotoksičnost u koncentracijama preko 12 μg/ml, one nisu genotoksične i ne indukuju stvaranje superoksidnih anjona. Sa druge strane, nanočestice selena nisu bile citotoksične ispod 150 μg/ml, ali su njima tretirane ćelije pokazale znake oštećenja DNK i povećanje produkcije superoksidnih anjona, čak i na 18 μg/ml. Kompozit je pokazao drugačije efekte, indukujući višu citotoksičnost i oksidativni stres nego ekvivalentne koncentracije komponenti, ali istovremeno nije bio genotoksičan. Moguće je da su interakcije nanočestica selena sa nanočesticama resveratrola dovele do pojave jedinstvenih osobina kompozita, potvrđujući izuzetnu važnost testiranja nanokompozitnih materijala uporedo sa njihovim komponentama.
AB  - The continuous interest in engineered nanoparticles of various materials, and their composites, has raised numerous questions regarding their toxicological profiles. Polyphenol resveratrol and selenium compounds are among the agents to which nanotechnology has given all new approach. Their particulate forms possess improved bioavailability and biological effects, such as antibacterial activity. Furthermore, selenium nanoparticles usually have significantly lower toxicity compared to selenium compounds. In this study, we prepared composite material consisting of selenium and resveratrol nanoparticles. Then, composite material and its components were assessed by using tetrazolium MTT dye for determining cytotoxicity, comet assay for genotoxicity study, and nitroblue tetrazolium assay (NBT) assay to estimate levels of superoxide anions. The normal human fibroblast cells (MRC-5) were used in all the experiments. Results showed that, although the resveratrol component exhibited cytotoxicity at 12 μg/ml, it was not genotoxic, and did not induce superoxide anion production. Selenium nanoparticles, on the other hand, were not cytotoxic below 150 μg/ml, but treated cells showed signs of DNA damage and elevation in superoxide anion production even at 18 μg/ml. Composite material behaved differently, inducing higher cytotoxicity and oxidative stress than comparable concentrations of components, but also showed lack of genotoxicity. Possible interactions of selenium nanoparticles with resveratrol nanoparticles could have created unique composite properties, confirming the great importance of toxicity testing of nanocomposite materials along with their components.

Na osnovu podataka iz literature, nanočestice selena su najčešće manje toksične nego jedinjenja sa selenom. U našem istraživanju, najpre smo pripremili kompozitni materijal na bazi selena i resveratrola. Nakon toga, kompozit i njegove komponente bili su testirani pomoću MTT tetrazolijumske boje za utvrđivanje citotoksičnosti, komet testom na genotoksičnost i nitroplavo-tetrazolijumskim testom za procenu nivoa superoksidnih anjona. U svim eksperimentima je korišćena zdrava ćelijska linija fibroblasta čoveka (MRC-5). Rezultati su pokazali da, iako čestice resveratrola ispoljavaju citotoksičnost u koncentracijama preko 12 μg/ml, one nisu genotoksične i ne indukuju stvaranje superoksidnih anjona. Sa druge strane, nanočestice selena nisu bile citotoksične ispod 150 μg/ml, ali su njima tretirane ćelije pokazale znake oštećenja DNK i povećanje produkcije superoksidnih anjona, čak i na 18 μg/ml. Kompozit je pokazao drugačije efekte, indukujući višu citotoksičnost i oksidativni stres nego ekvivalentne koncentracije komponenti, ali istovremeno nije bio genotoksičan. Moguće je da su interakcije nanočestica selena sa nanočesticama resveratrola dovele do pojave jedinstvenih osobina kompozita, potvrđujući izuzetnu važnost testiranja nanokompozitnih materijala uporedo sa njihovim komponentama., The continuous interest in engineered nanoparticles of various materials, and their composites, has raised numerous questions regarding their toxicological profiles. Polyphenol resveratrol and selenium compounds are among the agents to which nanotechnology has given all new approach. Their particulate forms possess improved bioavailability and biological effects, such as antibacterial activity. Furthermore, selenium nanoparticles usually have significantly lower toxicity compared to selenium compounds. In this study, we prepared composite material consisting of selenium and resveratrol nanoparticles. Then, composite material and its components were assessed by using tetrazolium MTT dye for determining cytotoxicity, comet assay for genotoxicity study, and nitroblue tetrazolium assay (NBT) assay to estimate levels of superoxide anions. The normal human fibroblast cells (MRC-5) were used in all the experiments. Results showed that, although the resveratrol component exhibited cytotoxicity at 12 μg/ml, it was not genotoxic, and did not induce superoxide anion production. Selenium nanoparticles, on the other hand, were not cytotoxic below 150 μg/ml, but treated cells showed signs of DNA damage and elevation in superoxide anion production even at 18 μg/ml. Composite material behaved differently, inducing higher cytotoxicity and oxidative stress than comparable concentrations of components, but also showed lack of genotoxicity. Possible interactions of selenium nanoparticles with resveratrol nanoparticles could have created unique composite properties, confirming the great importance of toxicity testing of nanocomposite materials along with their components.",
