Mimicking shark skin to create clean cutting boards
Keeping work surfaces clean during meat processing is a challenge, and now researchers deliver key insights into a solution that could change the current practice altogether: Instead of working to prevent bacteria buildup, they created surfaces that stop bacteria from attaching in the first place. Using lasers to etch and alter the surface of the metal, the team was able to create micro- or nanoscale textures that make it difficult for microbial cells to attach to the surface. The technique, known as laser-induced surface texturing, also alters the metal's water-repellent properties.
