Laser-textured metal surfaces mimic shark skin to combat bacterial biofilms

Keeping work surfaces clean during meat processing is a challenge. Bacteria from meat can attach, grow, and build up to create a biofilm that is difficult to remove, even on stainless steel surfaces used in industrial facilities. It can also aggregate, clumping together into an invisible mass that is stronger than individual cells, making it harder to kill using food-grade antibacterial surface cleaners.
