In 2023, it was confirmed that LIPSS formed on stainless steel by YAG laser irradiation suppressed bacterial growth. This shows that structures with antibacterial properties can be formed using lasers. As a method to confirm the microstructure, we focused on a method to determine surface roughness from the reduction of reflectance.
