Inspired by the lotus leaf, engineers with the TresClean project have created the first self-cleaning, antibacterial metal surface.
The metal, which could be game changer for the food industry, was created using lasers to cut precisely tailored patterns on the metal in to mimic the shape of the lotus leaf’s surface. The tiny pockets of air created by the etching minimize the contact area between the metal surface and the liquid, which in turn prevents bacteria from sticking to the metal.
The TresClean team plans to first market the metal to the foods industry, but also envisions it being used on any metals that could benefit from antibacterial properties, including medical equipment and saucepans.
