Bioactive glasses with three different compositions (45S, 49S and 58S) were prepared via sol- gel technique. Scanning electron microscopy (SEM), Transition electron microscopy (TEM), X-ray fluorescent (XRF) and X-ray diffraction (XRD) were utilized to study characterization synthesized bioactive glass nanoparticles. Evaluation of bioactivity prepared bioactive glass was performing in the simulated body fluid (SBF). In order to nano particles were immersed in SBF at 37 °C for 30 days. Then Fourier transform infrared (FTIR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to recognize and confirm the formation of apatite layer and bioactivity of prepared nano particles bioactive glass.
