AB  - A review of recent advances in instrumental methods and techniques for structural and physicochemical characterization of biomaterials and bone tissue is presented in this paper. In recent years, biomaterials attracted great attention primarily because of the wide range of biomedical applications. This paper focuses on the practical aspects of instrumental methods and techniques that were most often applied (X-ray methods, vibrational spectroscopy (IR and Raman), magnetic-resonance spectroscopy (NMR and ESR), mass spectrometry (MS), atomic absorption spectrometry (AAS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES), thermogravimetry (TG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC), scanning electron microscopy (SEM), transmission electron microscopy (TEM)) in the structural investigation and physicochemical characterization of biomaterials and bone tissue. The application of some other physicochemical methods was also discussed. Hands-on information is provided about these valuable research tools, emphasizing practical aspects such as typical measurement conditions, their limitations and advantages, interpretation of results and practical applications.

AB  - In this study, we have investigated the synthesis of nanoparticles of hydroxyapatite (HAp) and hydroxyapatite coated with chitosan (HAp/Ch) and the chitosan-poly-d,l-lactide-co-glycolide polymer blend (HAp/Ch-PLGA) as an organ-targeting system. We have examined and defined the final destination, as well as the dynamics and the pathways of the synthesized particles following intravenous administration in vivo.

The XRD, ZP, FT-IR and SEM analyses have confirmed that the hydroxyapatite nanoparticles with d50 = 72 nm are coated with polymers. Radioactive 125-Iodine (125I), a low energy gamma emitter, was used to develop a novel in situ method for the radiolabeling of particles and investigation of their biodistribution. 125I-labeled particles exhibited high stability in saline and serum over the second day, which justified their use in the following in vivo studies.

The biodistribution of 125I-labeled particles after intravenous injection in rats differed significantly: HAp particles mostly targeted the liver, HAp/Ch the spleen and the liver, while HAp/Ch-PLGA targeted the lungs. Twenty-four hours post injection, HAp particles were excreted completely, while both 125I-HAp/Ch and 125I-HAp/Ch-PLGA were retained in the body for a prolonged period of time with more than 20% of radioactivity still found in different organs.

AB  - The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500–1300 cm−1.

AB  - Nanoparticles based on hydroxyapatite (NPs) have many useful physicochemical and biological
properties, such as easy preparation and modification, as well as biocompatibility, which make them suitable for transport and unloading of various pharmaceuticals. Hydroxyapatite
nanoparticles coated with bioresorbable polymers have been successfully used as carriers of
antibiotics and vitamins in bone tissue engineering. In this study, we have investigated the synthesis of nanoparticles of hydroxyapatite and hydroxyapatite coated with chitosan and the chitosan-poly-D,L-lactide-co-glycolide polymer blend. The influence of the processing technique on the structure and characteristics of the obtained particles was studied by X-ray diffraction (XRD), particle size distribution analysis (PSD), Fourier transform infrared spectroscopy (FTIR), zeta potential analysis (ZP) and scanning electronic microscopy (SEM). In applied research, an appropriate radioisotope (Iodine-125) was selected and it was used to label particles. The in vivo biodistribution of 125I-labeled particles were studied in healthy Wistar rats following intravenous administration. The XRD, FT-IR and ZP analyses have confirmed that the hydroxyapatite particles with d50=72 nm are coated with chitosan and the chitosan-poly-D,L-lactide-co-glycolide polymer blend. 125I-labeled particles showed completely different behaviour in vivo: hydroxyapatite particles have the highest liver accumulation 10 min after injection but rapid excretion from the body without residual radioactivity 24 hours after injection; chitozan coated hydroxyapatite particles have the highest accumulation in the liver 10 min after injection with considerable amount (almost 50 %) retained 24 hours later; hydroxyapatite particles coated with the chitosanpoly-D,L-lactide-co-glycolide polymer blend have the highest uptake in the lungs 10 minutes after injection and moderate retention in the same organ 24 hours later.

AB  - Simulated body fluid (SBF) is an artificial fluid which has ionic composition and ionic concentration similar to human blood plasma. Purpose: This paper compares the interaction between the nanomaterial containing calcium phosphate/poly-dl-lactide-co-glycolide (N-CP/PLGA) and SBF, in order to investigate whether and to what extent inorganic ionic composition of human blood plasma leads to the aforementioned changes in the material. Methods: N-CP/PLGA was incubated for 1, 2, 3, and 5 weeks in SBF. The surface of the material was analyzed on SEM-EDS and FTIR spectrometer, while SBF was subjected to pH and electrical conductivity measurement. Results: Our results indicate that dissolution of the polymer component of the material N-CP/PLGA and precipitation of the material similar to hydroxyapatite on its surface are based on the morphologic changes seen in this material. Conclusions: The mechanism of the apatite formation on the bioceramic surface was intensively studied and was considered crucial in designing the new biomaterials. The results obtained in this work indicate that N-CP/PLGA may be a good candidate for application to bone regeneration.

AB  - The purpose of biomaterials is to replace a part or a function of the body in a safe, physiologically and economically acceptable way. The process of the reconstruction of bone defects has always been a big problem in orthopedics and maxillofacial surgery. Since hydroxyapatite (HAp) was detected as a component, the predominant constituent and the integral element of Mammalian bones, the development of the phospate ceramics as potential materials for implantation was enabled. This study investigated whether and in which way biomaterial calcium hydroxyapatite/poly-L-lactide (HAp/PLLA) interacts with the ionic composition of the human plasma. The simulated body fluid (SBF) is an artificial fluid that has the ionic composition and ionic concentration similar to the human blood plasma. HAp/PLLA was incubated for 1, 2, 3 and 5 weeks in SBF. The surfaces of both treated and untreated materials were analyzed on a scanning electron microscopy (SEM), and were also exposed to the energy dispersive X-ray spectroscopy (EDS), while SBF was submitted to the measuring of pH and electrical conductivity. However, our results indicate that the degradational changes of the material HAp/PLLA in SBF start from the surface of the treated material and that observed changes are the consequence of dissolution of its polymer component and the precipitation of the material similar to hydroxyapatite on its surface. This material shows good characteristics that place it among good candidates for the application in orthopedics and maxillofacial surgery.
