Effect of ZnO Doping on Biological Properties of SiO2-CaO-P2O5-SrO Bioactive Nanoglasses Synthesized via the Sol–Gel Method

The current research was done to evaluate the effect of zinc on the structural and biological characteristics of 58 s bioactive glasses. To this end, SiO 2 –CaO–P 2 O 5 –SrO–ZnO bioactive nanoglasses containing different content of ZnO (0, 1, 3, and 5 mol.%) were produced by the sol–gel process. To...

Description
Summary:The current research was done to evaluate the effect of zinc on the structural and biological characteristics of 58 s bioactive glasses. To this end, SiO 2 –CaO–P 2 O 5 –SrO–ZnO bioactive nanoglasses containing different content of ZnO (0, 1, 3, and 5 mol.%) were produced by the sol–gel process. To assess their bioactivity, the specimens were soaked in the simulated body fluid (SBF) solution for 21 days and analyzed employing Fourier transform infrared spectroscopy (FT-IR), x-ray diffraction (XRD), and scanning electron microscopy (SEM) techniques. The results indicated that the bioactive nanoglass sample containing 1 mol.% Zn possessed the highest potential in terms of hydroxyapatite formation. The results obtained by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay proved the superior biocompatibility of Zn-containing nanoglasses compared to Zn-free samples. Accordingly, the sample containing 1 mol.% Zn was considered a suitable candidate for medical applications.
