The properties of biomimetically processed calcium phosphate on bioactive ceramics and their response on bone cells.

摘要: This study looks for grounds to alter the chemical composition (phosphate, calcium, silica and carbonate), dissolution properties, structure nanotopography of biomimetically processed surfaces on bioactive ceramics optimize their shown ability influence bone cell behaviour production new bone. In environment desirable characteristic these materials is be remodeled by natural osteoclastic resorption. Different carbonate containing calcium phosphate layers were prepared glasses 9 (S53P4) 1-98 (S53P2) sol-gel pure SiO2 in C- R-SBF (conventional revised simulated body fluid) varying periods time. It was that CaP layer formed faster compared C-SBF. The contained more (CO3(2-)) with same immersion time so precipitation amorphous than bonelike HCA results indicate most suitable surface both osteoblasts osteoclasts found an having mesoporous proper rate silica.
