Using inspiration from nature, a team of European researchers has harnessed new photonics technology to develop what they claim is the first fluid-repellent, antibacterial, metal surface, which is likely to find a use soon in food processing applications.

Taking their ideas from defence mechanisms found in plants such as the lotus leaf, the ‘high throughput laser texturing of self-cleaning and antibacterial surfaces’, or TresClean project, has made a breakthrough that will enable the production of self-cleaning sheet metal on an industrial scale for the first time.

This new technique will initially be used to create antibacterial surfaces for use for machine parts used in food production, dramatically increasing productivity and reducing costs in factories that process food products such as milk, tomato sauce, and yogurt.

TresClean has used high-power laser cutting devices to create a specifically tailored, rough micro-topography on sheet metal that mimics the surface of the lotus leaf, causing liquids to ‘bounce off’.
