Investigation of Morphology, Structure and Particle Size of Bioglass-58S Nanopowder Prepared by Sol-Gel Method for Biomedical Applications

The aim of this research is synthesis of bioglass-58S nanopowders by sol-gel method. Also, effect of aging time on morphology, structure and particle size of powders for biomedical applications was investigated. Bioglass-58S powders were analyzed by X-ray diffraction pattern (XRD), Fourier transform infrared spectroscopy (FTIR), zetasizer instrument, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The XRD result showed the powder is amorphous and glassy. According to FTIR spectroscopy, silicates bonds were formed in all powders. Zetasizer results proved that the particle sizes of powders and agglomerates were increased by aging time. The SEM images confirmed these results, too. As well, TEMobservations showed the increasing of aging time caused the growth of grain sizes between 50-200 nm. Since, these powders synthesized in nanometric scale, the reaction of materials and body can accelerate, whereupon improve bone formation process.
