BOROSILICATE GLASS AS A CARRIER FOR NANOCERIA**

Abstract

A bio active borosilicate glass doped with different concentrations of cerium oxide was investigated as a potential carrier for nanoceria . Nanoceria exhibit coexistence of Ce3+ and Ce4+ ions and the Ce3+/Ce4+ ratio plays an important role in determining its anti-oxidant activity in a biological system. A borosilicate glass doped with 3-6 wt% cerium oxide was used to produce cerium oxide nano particles. These nano particles as well as the glass that contained the nanoparticles was examined using SEM, Raman, XRD, and DSC. The release of cerium by the bioactive borosilicate glass into simulated body fluid was also determined by ICP.
