In this study, biocompatibility of nano composites of silica doped in HA/collagen was compared against those doped in HA/gelatin. For this purpose, hydrothermal samples were synthesized before being investigated by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the samples were further characteri...
Article
In this study, we compared the effects of silica and gelatin in nano hydroxyapatite (nHA) composite with pure hydroxyapatite. We have synthesized hydrothermal nHA gelatin template and silica. They (The obtained samples) were investigated by x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Scanning and transmission electr...

... It may be due to the creation of the stronger bonds in the glass-ceramic samples and the Ca 2+ and (PO 4 ) 3 − cannot easily release from them. Nevertheless, the Ca and P counts in EDS analysis of HA that formed from SBF solution are more than the Ca and P counts reported in other studies [52,53]. ...
... XRD patterns for silica nanoparticles doped in hydroxyapatite/collagen and hydroxyapatite/gelatin showed crystalline planes for hydroxyapatite which was independent of doping material. Further, the crystallite size of hydroxyapatite gelatin silica nanocomposite and hydroxyapatite collagen silica composite was found to be 10.73 and 4.19 nm respectively [137]. In the X-ray diffraction pattern of HA/ZnO nanocomposite, prominent peaks were observed and assigned to the hexagonal wurtzite structure of nanometer ZnO particles with a degree of crystallinity [47]. ...
