文摘The nanogrooved surface of polystyrene(PS) petri-dishes was induced by an ultraviolet laser irradiation method. The influence of the surface nanostructure on the growth of the human tongue squamous cells carcinomas (HTSCC) was investigated. Cells cultured on laser-irradiated PS surface show an enhanced attachment and spreading in HTSCC cell culture test, and cell orientation was successfully controlled by selectively treating the PS surface. We also prove that the nanostructures on polymer surface improved the cell attachment and spreading.
