AB  - We report an innovative low-cost wet  precipitation  synthesis  method  for  gelatin-modified   zinc oxide nanoparticles (GM ZnO NPs) at the inter- face  between  the  gelatin  hydrogel  and  aqueous  elec- trolyte.  Diffusion  of  ammonia  through  the  hydrogel   matrices with different gelatin contents induced pre- cipitation  of  the  product  in  contact  with  the  surface   of  the  aqueous  solution  of  zinc  ions.  The  obtained   precipitate  was  subjected  to  thermal  treatment  to  partially  decompose  the  adsorbed  gelatin  in  the  NP   structure. Physicochemical properties of obtained  GM  ZnO  NPs  were  characterized  by  X-ray  powder   diffraction (XRD), scanning electron microscopy  (SEM), Fourier transform infrared spectroscopy  (FTIR), differential thermal analysis (DTA), thermo- gravimetry (TG), photon correlation spectroscopy  (PCS),  zeta  potential  measurements,  and  inductively   coupled  plasma-mass  spectrometry  (ICP-MS).  The   estimated mean crystallite size of GM ZnO NP pow- ders was in the range from 5.8 to 12.1 nm. The syn- thesized  NPs  exhibited  nanosheet  morphology  and   arranged into flake-like aggregates. The toxic poten- tial was investigated in vitro in human hepatocellular  carcinoma cell line HepG2. The thiazolyl blue tetra- zolium bromide (MTS) assay was used to assess cell  viability,  2′,7′-dichlor-fluorescein-diacetate  (DCFH- DA)  assay  to  examine  the  formation  of  intracellu- lar  reactive  oxygen  species  (ROS),  and  comet  assay   to  evaluate  the  genotoxic  response.  GM  ZnO  NPs   slightly reduced HepG2 cell viability, did not induce  ROS formation, and showed low genotoxic potential  at  very  high  doses  (100  μg    mL−1).  ZnO  NPs  fabri- cated  and  modified  using  the  proposed  methodol- ogy deserve further study as potential candidates for  antibacterial agents or dietary supplements with low  overall toxicity.

AB  - Composite hydrogels capable of controlled drug delivery via ion exchange are an interesting group of materials for the construction of implantable drug reservoirs for electrically charged drugs. In this study, we synthesized composite poly(DL-lactide-co-glycolide)/poly(acrylic acid) (PLGA-PAA) hydrogels by sequential application of UV or gamma irradiation and traditional phase inversion. Physicochemical properties of the composite PLGA-PAA hydrogels were investigated using Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). We examined the ion exchange capacity (IEC) and swelling behavior of these materials to determine their potential as drug reservoirs. Composite PLGA-PAA hydrogel synthesized using UV irradiation (UV-PLGA-PAA) exhibited a porous microstructure with submicron-sized hydrogel-rich aggregates and homogeneous chemical composition. Swelling behavior and IEC of this material were highly reproducible. Composite PLGA-PAA hydrogels synthesized using gamma irradiation (G-PLGA-PAAs) had a less uniform microstructure with larger pores and micron-sized hydrogel-rich aggregates while exhibiting rather inhomogeneous chemical composition. These materials showed superior swelling properties, but a more variable IEC, compared to the material fabricated using UV irradiation. Results of DSC analysis showed a dose-dependent decrease in glass transition temperature for G-PLGA-PAAs indicating the effects of PLGA chain scission. Our findings indicate that gamma irradiation is a possible alternative to UV irradiation in the synthesis of composite PLGA-PAA hydrogels which can modify or control important material properties. However, the synthesis protocol using gamma irradiation should be further optimized to improve the IEC reproducibility. In our future research, we will investigate the in vitro release of charged drugs from synthesized composite PLGA-PAA hydrogels under physiological conditions.

AB  - Nanotechnology has great potential in the biomedical field. Among other nanomaterials, inorganic nanoparticles have become extremely important since they possess unique physicochemical properties influenced by their specific surface structure. Consequently, inorganic nanoparticles exhibit enhanced functionalities such as biological response, antibacterial and antiviral properties, as well as optical, magnetic, and electrical responses. They have found applications in medicine, pharmacy, controlled drug delivery, optics, electronics, etc. In this chapter, reports on obtaining different metallic and ceramic inorganic nanoparticles such as gold, silver, selenium, copper, iron, zinc oxide, and hydroxyapatite for biomedical applications will be addressed. For each of these nanosystems, the main challenges regarding the currently achieved functional properties and further perspectives will also be presented.

abstract = "Nanotechnology has great potential in the biomedical field. Among other nanomaterials, inorganic nanoparticles have become extremely important since they possess unique physicochemical properties influenced by their specific surface structure. Consequently, inorganic nanoparticles exhibit enhanced functionalities such as biological response, antibacterial and antiviral properties, as well as optical, magnetic, and electrical responses. They have found applications in medicine, pharmacy, controlled drug delivery, optics, electronics, etc. In this chapter, reports on obtaining different metallic and ceramic inorganic nanoparticles such as gold, silver, selenium, copper, iron, zinc oxide, and hydroxyapatite for biomedical applications will be addressed. For each of these nanosystems, the main challenges regarding the currently achieved functional properties and further perspectives will also be presented.",

AB  - Poly(DL-lactide-co-ε-caprolactone)/poly(acrylic acid) implantable composite reservoirs for cationic drugs are synthesized by sequentially applying photoirradiation and liquid phase inversion. The chemical composition and microstructure of reservoirs are characterized with Fourier transform infrared spectroscopy-attenuated total reflection (FTIR-ATR) and scanning electron microscopy (SEM), respectively. Drug loading and release properties are investigated using methylene blue as the drug model. Biocompatibility of reservoirs is examined through a series of in vitro tests and an in vivo experiment of subcutaneous implantation in Dark Agouti rats. Reservoirs show good ion-exchange capacity, high water content, and fast reversible swelling with retained geometry. Results of drug loading and release reveal excellent loading efficiency and diffusion-controlled release during 2 weeks. Biocompatibility tests in vitro demonstrate the lack of implant proinflammatory potential and hindered adhesion of L929 cells on the implant surface. Implants exhibit low acute toxicity and elicit a normal acute foreign body reaction that reaches the early stages of fibrous capsule formation after 7 days. © 2018 WILEY-VCH Verlag GmbH & Co.

AB  - Nanostructured zinc oxides are promising materials for numerous biomedical applications where they can serve as therapeutic agents or tools for sensing and imaging. Despite their favorable properties, wider use of zinc oxide nanoparticles in biomedicine is limited by toxicity issues. Therefore, new synthesis approaches should be devised to obtain zinc oxide nanoparticles which are safe-by-design. We present an innovative low-cost wet precipitation synthesis of gelatin modified zinc oxide nanoparticles at the gel/liquid interface. The diffusion of ammonia through the gelatin hydrogels of different porosities induces precipitation of the product in contact with the surface of the aqueous solution of zinc ions. After thermal treatment of the precipitate, adsorbed organic residues of decomposed gelatin act as modifiers of zinc oxide nanoparticles. We characterized the physicochemical properties of obtained gelatin modified zinc oxide nanoparticles by XRD, FTIR, DTA/TG, and SEM. The synthesized nanoparticles show hexagonal wurtzite structure and form flakelike aggregates. FTIR and DTA/TG analyses indicate that the thermal decomposition of adsorbed gelatin depends on the gelatin content of the hydrogel used in the synthesis. We also examined the viability of HepG2 cells, generation of intracellular reactive oxygen species, and genotoxicity using the MTS, DCFH-DA, and alkaline comet assay, respectively. Fabricated gelatin modified zinc oxide nanoparticles show very low toxicity potential at doses relevant for human exposure.

Passive release kinetics wasdiffusion-controlled with pH-sensitive and loading-dependent behavior. Linear release kinetics wasdemonstrated during the iontophoretic release.

AB  - Composite implants comprising a biodegradable hydrophobic polymer matrix and crosslinked hydrogel with fixed ion exchange groups are promising materials for the construction of controlled drug delivery systems. Poly(lactic-co-glycolic acid)/poly(acrylic acid) (PLGA/PAA) composite implants in our study were synthesized using the sequential application of irradiation and immersion precipitation. Precursor solutions with all functional components were dispensed into a disc-shaped non-stick mold and cured either by ultraviolet (UV) or gamma irradiation. Cured disks were subsequently immersed in the phosphate buffer saline bath to finalize phase separation and solidification of the implants. The synthesized implants were characterized by FTIR-ATR and DSC, and their basic properties such as ion exchange capacity, swelling degree, and swelling kinetics were examined. Synthesis using gamma irradiation resulted in implants with similar ion exchange capacity, but the greater swelling degree and faster swelling kinetics compared to the implants prepared with UV irradiation.

AB  - Composites of biodegradable polymers and hydrogels are promising materials for controlled delivery systems with prolonged drug release. In this contribution, we present an innovative implant design comprising poly(DL-lactide-co-ε-caprolactone) copolymer base and a crosslinked poly(acrylic acid) hydrogel. Implants were prepared in the form of disks using the modified traditional liquid phase inversion process. Solutions containing all implant precursors were dispensed into transparent non-stick molds and cured by UV irradiation. UV curing was followed by immersion into the phosphate buffer solution bath to achieve phase separation and solidification. Structure and composition of the implant were characterized using SEM and FTIR. Obtained implants exhibited high loading capacity for cationic formulations and a moderate degree of swelling. Studies of implant loading and subsequent release of methylene blue into the phosphate-buffered saline demonstrated diffusioncontrolled delivery kinetics over a period of several weeks. To assess biocompatibility of implants as possible materials for drug delivery systems in mammals, we evaluated their effects on viability (Trypan blue exclusion assay), metabolic activity, proliferation (MTT assay) and priming (nitric oxide/NO production) of freshly isolated rat splenocytes during 24 h and 48 h of cultivation. The viability was unaltered, metabolic activity/proliferation was increased after 48 h and the decrease of NO production, as well as drop in responsiveness to cell mitogen concanavalin A (ConA) in cells on implants were observed. These results suggest that implants could be used as a suitable material for drug delivery systems, but their capacity to stimulate cell proliferation and their immunosuppressive potential deserve further investigations.

AB  - This study presents an innovative approach towards wet chemical synthesis of hydroxyapatite bioceramics by application of alternating current (AC) electric field during the synthesis at low and intermediate temperatures. Specially designed low-cost electrical setup provided stable, reliable and modular system which supplied electric energy within the reaction volume as characterized by computer simulation of reaction conditions. Energy introduced through external excitation (alternating voltage amplitude of 10 V and frequency of 1 kHz) influenced crystallization, ionic composition, sintering behavior of hydroxyapatite powders, microstructure and final phase composition of sintered ceramics. Crystallite size in [002] crystallographic direction increased with electric field assistance regardless of the synthesis temperature. Non-isothermal sintering studies showed significantly improved densification and implied better thermal stability of powders synthesized in the presence of AC field, shifting the Ca/P ratio towards stoichiometric one. Vibrational spectroscopy analysis indicated the role of charge, mobility and effective ionic radius of present ions in transferring the energy supplied with external field influencing further thermal stability of the crystal lattice. Microstructural investigation and phase composition analysis suggested that application of AC electric field during the synthesis of nanocrystalline hydroxyapatite improved material properties and offered potential for tailoring macro/micro-porosity with precise modulation of electrical parameters.

AB  - Polymeric pH-sensitive membranes and hydrogels are interesting materials for the controlled delivery of chemical agents triggered by external stimuli. In this contribution, we present a novel membrane design consisting of a polyethersulfone polymeric base and a crosslinked poly(acrylic acid) hydrogel containing pH-responsive carboxyl groups. Membranes were prepared using the modified traditional liquid phase inversion process. Solutions containing all membrane precursors were cast on a glass plate and cured by UV irradiation. UV curing was followed by immersion into the water bath to achieve phase separation and solidification. Obtained membranes exhibited high ion-exchange capacity and a moderate swelling degree dependent on the crosslinker properties. Studies of membrane loading with methylene blue and subsequent release of methylene blue from the membrane into the alkaline and acidic buffered solutions demonstrated pH-dependent delivery kinetics.
