Nghiên cứu chế tạo màng sinh học hydroxyapatit (HA) bằng phương pháp sol-gel trong môi trường etanol

Abstract

The ethanol - based sol-gel method was used for synthesis of nanocrystalline hydroxyapatite. The HA coating has been prepared on alumina ceramic substrate by dipping into ethanol sol-gel suspension of Ca(NO₃).4H₂O and (NH₄)₂ HPO₄. To achieve better biocompatibility and excellent mechanical performance of prostheses, HA coating is often fabricated on surface of bone substitute implant.
