RAMAN SPECTROSCOPIC STUDIES OF BIOACTIVE MATERIALS

Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman spectroscopic technique. It is found that most samples exhibit bioactivity when they are soaked in SBF. It is also concluded that Raman spectroscopy is a powerful technique in such studies.
