This research has been done to study characteristic and biocompatible evaluation of a nano-biocompositeceramic with the bioglass (BG) as a first phase. In this regard, synthesis of S53P4 (53% SiO2, 4% P2O5,23% Na2O and 20% CaO) bioglass has been considered as the first phase and flourapatite (FA) consideredas the second phase. Afterwards, nanocomposite with the base of S53P4 bioglass has been synthesizedby sol-gel method. The synthesized nanoparticles and nanocomposite have been characterized with thehelp of different techniques, using field emission scanning electron microscope (FESEM), X-ray diffraction(XRD), Fourier transforms infrared spectroscopy (FT-IR), X-ray fluorescence (XRF) to evaluate crystalstructure, microstructure, and morphology. The results showed that the crystallite size and the crystallinityof S53P4 bioglass-fluorapatite nanocomposites were about 20-30 nm and 70-90%, respectively.The FT-IR analyses displayed that the purity in the structure of this nanocomposite. The result of MTT(3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide) assay indicated the nontoxicity and alsodecreasing of cell viability in 7 days compared with the first day.
