Reports from China University of Mining and Technology Highlight Recent Findings in Nanotubes (Improvement of biological properties of titanium by anodic oxidation and ultraviolet irradiation)

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanotubes. According to news reporting originating in Xuzhou, People's Republic of China, by NewsRx journalists, research stated, "Anodic oxidation was applied to produce a homogeneous and uniform array of nanotubes of about 70 nm on the titanium (Ti) surface, and then, the nanotubes were irradiated by ultraviolet. The bioactivity of the Ti surface was evaluated by simulated body fluid soaking test."

The news reporters obtained a quote from the research from the China University of Mining and Technology, "The biocompatibility was investigated by in vitro cell culture test. The results showed that bone-like apatite was formed on the anodic oxidized and UV irradiated Ti surface, but not on the as-polished Ti surface after immersion in simulated body fluid for two weeks. Cells cultured on the anodic oxidized Ti surface showed enhanced cell adhesion and proliferation, also presented an up-regulated gene expression of osteogenic markers OPG, compared to those cultured on the as-polished Ti surface. After UV irradiation, the cell behaviors were further improved, indicating better biocompatibility of Ti surface. Based on these results, it can be concluded that anodic oxidation improved the biological properties (bioactivity and biocompatibility) of Ti surface, while UV irradiation improved the biocompatibility to a better extent. The improved biological properties were attributed to the nanostructures as well as the enhanced hydrophilicity."

According to the news reporters, the research concluded: "Therefore, anodic oxidation combined with UV irradiation can be used to enhance the biological properties of Ti-based implants. ."
