【 摘 要 】

The biomimetic precipitation of calcium phosphate (CaP) coating was performed by soaking of β-Tricalcium phosphate (TCP) ceramic scaffolds in supersaturated solution. Surface functionalization was obtained by incorporation of bovine serum albumin (BSA) as a model protein. The structure and phase composition were studied by application of XRD, FTIR, SEM, BET absorption. BSA incorporation content as a result of co-precipitation was evaluated.
