New Composite Membranes Containing Bioactive Glass-Ceramic Nanoparticles and Chitosan for Biomedical Applications

Abstract:

In this study a new P-free system applied to the production of Bioactive Glass Nanoparticles (BG-NPs) is proposed, in order to evaluate the effect of suppressing this component, in the bioactivity capability of the materials. The BG-NPs, based on both ternary (SiO2-CaO-P2O5) and binary (SiO2-CaO) systems, were prepared via a sol-gel method. The morphology and composition of the BG-NPs were studied using FTIR and SEM. New composite membranes were produced combining chitosan and the BG-NPs. The bioactive character of the prepared biodegradable membranes was accessed in vitro by analyzing the capability for apatite formation onto the surface after being immersed in simulated body fluid (SBF). EDX and SEM were used to confirm the bioactivity of the materials.
