Niobium addition to sol-gel derived bioactive glass powders and scaffolds: In vitro characterization and effect on pre-osteoblastic cell behavior

Bioactive glasses are synthetic biocompatible materials that are able to interact with host tissue due to ion release when in contact with living tissues. Both composition and microstructure of glasses are important for its ability to promote bone deposition [1]. Sol –gel route has been used as an easier and successful route to produce both bioactive glass powders [2] and porous tridimensional structures [3]. Bioactive glass powder synthetized by sol–gel route results in particles with superficial porosity and high surface area, while gel cast foaming has be en shown to produce scaffolds with controlled porosity and pore size to mimic bone structure allowing material to act as a framework for deposition of new tissue [4].
