Femtosecond laser induced periodic nanostructures and microstructures on ti plate for control of cell spreading

Abstract

Periodic nanostructures and microstructures formation on Ti plate by scanning of femtosecond laser beam spot is reported. Femtosecond lasers are useful tools for creating periodic structures with the period in the range from nanoscale to microscale on metals. The periodic nanostructures and microstructures were formed on the Ti plate by femtosecond laser irradiation for scanning speed of 0.5 mm/s at laser fluence of 0.35 J/cm2. The periods of periodic nanostructures and microstructures on the Ti plate were about 600 nm and 10µm, respectively. The results in cell test suggest that cell was spread along the direction of the periodic nanostructures’ grooves.Periodic nanostructures and microstructures formation on Ti plate by scanning of femtosecond laser beam spot is reported.
