Shark-Skin Inspired Laser Etching Creates Antibacterial Cutting Boards

Researchers have developed a novel solution to prevent bacterial buildup on food processing surfaces. Inspired by the naturally antimicrobial textures of shark skin and cicada wings, they used lasers to etch micro- and nanoscale textures onto metal surfaces. This prevents bacteria from attaching, effectively eliminating the need for constant cleaning and reducing biofilm formation. The laser texturing technique avoids the use of chemicals, making it a safer and more sustainable alternative. Future work involves machine learning models to optimize the process for industrial applications.
