Abstract
Several different compositions of zinc-containing glasses in the CaO-SiO2 system were obtained by both traditional melting technique and the sol-gel method. The influence of zinc ions addition in the glass composition was evaluated using different spectroscopic methods (FTIR and Si-29 MAS-NMR). It was demonstrated that ZnO has a significant effect on glass structure and, as a consequence, on thermal properties, texture and bioactivity. EDX and ICP data showed that zinc ions reduce glass bioactivity and incorporate in the newly forming HCA layer. Evaluation of the in vitro biocompatibility of the obtained materials was performed by indirect tests using MG-63 osteoblast-like cells. All samples were found to be biocompatible and zinc ions enhanced the cell viability. Antibacterial tests against gram-negative (E. coli) and gram-positive bacteria (S. aureus) were carried out to evaluate the antibacterial potential of the zinc-doped glasses.
