Design and Fabrication of Bioactive and Antibacterial LIPSS Surfaces on Titanium Alloy by Femtosecond Laser

culture experiments. It is demonstrated that the horizontal LIPSS sample with a width of 30 μm has the highest cell proliferation rate (142.5% after 1 day, 132.3% after 3 days) and a good antibacterial rate (50.2%). These results provide guidance for the application of the LIPSS in biocompatibility and antibacterial aspects.
