Abstract

Pure titanium (Ti) and Ti alloys have been widely used as biomaterials. However, they have the disadvantage of lacking for bioactivity. Thus, adding a new function to Ti and Ti alloys is required. One method for adding new functions is controlled cell spreading by formation of periodic surface nanostructures on the biomaterials. In this study, the nanostructures were formed on the pure Ti by ultrashort pulsed laser irradiation, and influence of laser parameters on surface profile and discontinuity of the nanostructures was discussed. Moreover, influence of the shape variation of the nanostructures on control of cell spreading was investigated.
