Abstract:
Objective:To prepare a kind of titanium implant doped with cobalt and to study its cytotoxicity.Methods:The surface of the titanium was anodized to form TiO2 nanotube arrays.Different amount of cobalt was doped by hydrothermal treatment,which was controlled by tuning the hydrothermal treatment duration.The cytotoxicity of the cobalt doped nanotubular implant coating on bone marrow stromal cells (BMSCs)was measured by CCK-8.Results:The nanotubular implant coating with different amount of cobalt was fabricated.The proliferation of BMSCs was inhibited by the nanotubular morphology and cobalt doping.Samples formed by hydro-thermal treatment in 0.1 M cobalt acetate showed significantly cytotoxicity.Conclusion:Hydrothermal treatment of anodized titanium is an effective way for developing novel cobalt doped nanotubular implant coating.The proper dose of cobalt doping needs to be further investigated.
