AB  - Copolymer poly (DL-lactide-co-glycolide) (PLGA) is extensively investigated for various biomedical applications such as controlled drug delivery or carriers in the tissue engineering. In addition, zinc oxide (ZnO) is widely used in biomedicine especially for materials like dental composites, as a constituent of creams for the treatment of a variety of skin irritations, to enhance the antibacterial activity of different medicaments and so on. Uniform, spherical ZnO nanoparticles (nano-ZnO) have been synthesized via microwave synthesis method. In addition to obtaining nano-ZnO, a further aim was to examine their immobilization in the PLGA polymer matrix (PLGA/nano-ZnO) and this was done by a simple physicochemical solvent/nonsolvent method. The samples were characterized by X-ray diffraction, scanning electron microscopy, laser diffraction particle size analyzer, differential thermal analysis, and thermal gravimetric analysis. The synthesized PLGA/nano-ZnO particles are spherical, uniform, and with diameters below 1 µm. The influence of the different solvents and the drying methods during the synthesis was investigated too. The biocompatibility of the samples is discussed in terms of in vitro toxicity on human hepatoma HepG2 cells by application of MTT assay and the antimicrobial activity was evaluated by broth microdilution method against different groups of microorganisms (Gram-positive bacteria, Gram-negative bacteria, and yeast Candida albicans).

AB  - Tissue engineering (TE) is a growing field which provides helpful alternative strategies for conventional treatments in medicine. TE involves the smart combination of cells, biomolecules and engineered porous biomaterials in the form of 3D scaffolds. When it comes to bone regeneration the use of 3D scaffolds made of calcium phosphate is a well-known concept with a great potential. Here we present the foam replica method as a procedure suitable for producing highly porous scaffolds with the pore size in the range of 100-500 μm and the mean porosity of >90%. The obtained scaffolds were further coated with selenium nanoparticles (SeNp) and SeNp immobilized within poly(epsilon caprolactone) microspheres (PCL/Se). The purpose of such coating is based on the potential anticancer activity of SeNp as well as on their prolonged release from a biodegradable polymeric carrier. Scaffolds were characterized by X-ray diffraction, scanning electron microscopy, optical microscopy, thermogravimetric/differential thermal analysis (TGA-DTA) as well as Fourier transform infrared spectroscopy (FTIR). The cytotoxicity was determined employing 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and all the samples have shown good biocompatibility. Based on these preliminary results the obtained system can be considered as a candidate for the repair of bone lesions and damages.
