ABSTRACT
Porous surfaces have an important effect on bioactivity of titanium implants. In this study, two micro/nanostructural titanium surfaces were prepared by chemical and electrochemical method. The two samples had different diameters of nanotubes. Tests of biomineralization and codeposition in simulated body fluid and bovine serum albumin (BSA) were carried out in order to evaluate the bioactivity of micro/nanostructural titanium surfaces. The information of the surfaces was detected using scanning electron microscope and X-ray diffractometer. The results showed that the bioactivity of micro/nanostructural titanium increased with the diameter of nanotubes. Furthermore, the existence of BSA can accelerate biomineralization and decrease the crystallinity of hydroxyapatite coating.
