    Abstract:

    Titanium oxide films doped with tantalum were synthesized on titanium and silicon wafer by sputtering deposition. The structure was investigated by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Blood compatibility of the films was evaluated by clotting time measurement, platelet adhesion investigation and protein adsorption. In vivo experiment was further performed. The result showed that the Ta doped titanium oxide film has attractive blood compatibility which exceed low isotropic pyrolytic carbon. The mechanism of the behavior of blood compatibility of Ta doped film was discussed.
