Abstract

The main requirements for titanium biomaterials are: (a) biocompatibility, (b) resistance to biological corrosion and (c) antisepticity. These requirements may be met by a new generation of titanium biomaterials with a specific surface layer of strictly defined microstructure, chemical and phase composition. Recently, various surface modifications have been applied to form a bioactive layer on Ti surface, which is known to accelerate osseointegration. The purpose of this study was to investigate bioactivity of porous calcium phosphate coatings prepared by a direct electrodeposition on Ti surface from a modified Hanks' solution. The thick 200 nm coatings, were prepared via cathodic polarization at constant voltage -1.5 V vs. OCP in a Hanks' solution. In order to evaluate the potential use of the coatings for biomedical applications, the adsorption of bovine serum albumin (BSA), the most abundant protein in blood, and living cells attachment (osteoblasts, U20S) were studied. The observed differences in living cells attachment suggest a more promising initial cellular response of Ca-P coatings with a pre-adsorbed albumin. The topography and a cross-section view of the Ca-P coatings were characterized using SEM and STEM techniques. The surface analytical techniques (AES, XPS, and FTIR) were used to characterize their chemical composition before and after protein BSA adsorption. © Warszawa - Krakow 2013.
