“…In order to improve the mechanical properties of scaffolds based on those polymers and ensure better adherence and proliferation of cells, composites containing calcium phosphates, bioglass or other fillers are used. Recently, the development of a new generation of nanomaterials in the field of photonics and bioelectronics also helps in development of materials with unique biomedical properties …”

The paper presents results of the studies on porous composites obtained using lyophilization method based on the solutions of the following polymers: chitosan, sodium alginate and polylactide, as well as ZnO-doped CaO-SiO 2 -P 2 O 5 bioglass.The researchers took the advantage of zinc ions demonstrating the bactericidal, immune-stimulating, and tissue-regenerating functions in the organism. The cytotoxicity of the composites was tested on L929 cells by means of the direct and the indirect contact method. The antibacterial properties were determined against the gram-negative bacteria Pseudomonas aeruginosa and the gram-positive bacteria Staphylococcus aureus at 24, 48 hours, and 7 days. The study demonstrated that changes due to cytotoxicity effect of the composites depend on the type of polymer and on the duration of contact with cells. The composite with polylactide was found to be the least toxic for L929 cells. ZnO added to the chemical composition of bioglass ensured bactericidal effects. The antibacterial properties of the composites depended on the ZnO content, bioglass grain size, polymer type, and composite microstructure. The composites presented in this paper are innovative as biomaterials for filling bone cavities because they can be a matrix for cells and have an antibacterial effect while supporting the regeneration of damaged tissue.

“…This reveals that Ti substrate has not much antibacterial activity. Studies about the bactericidal activity of ZrO 2 nanoparticles disclosed that they exhibit greater activity against S. aureus and B. subtilis [30,31,32]. In the case of CeO 2 nanoparticles, studies suggested that they have competent activity against gram negative bacteria like E. coli than gram positive bacteria S. aureus [33].…”

This article reports the synthesis, characteristics and biomedical applications of CeO2-ZrO2 and TiO2-ZrO2 nanoparticles. The nanoparticles are synthesized by Green combustion method. Aloe Vera, dates and pomegranate extracts are used as mediators to avoid toxicity instead of chemical reagents. Hence it is biocompatible, non-toxic and avoiding adverse effect in biomedical applications. The nanoparticles are characterized by XRD to confirm the physical structure. The FTIR, Raman and SEM with EDAX analyses the chemical composition and their morphology. The antibacterial activity of these nanoparticles is assayed by well diffusion method against the bacterial pathogens of Stephylococcusaureus, Shigillaflexneri and Bacillus sp. The anticancer effect of the nanoparticles is investigated on A549 cell line by In Vitro assay. The conceivable purpose is the hydroxyl radicals which are easily produced by oxidizing more hydroxide ions in alkaline solution. Thus the competence of the development is rationally improved at pH is 9.
