Lotus leaf inspires scientists to create world’s first self-cleaning metals

Nanowerk  January 7, 2019
Taking their ideas from defense mechanisms found in plants such as the lotus leaf an international team of researchers (Italy, France, Germany, Spain, UK) has developed the first fluid-repellent, antibacterial, metal surface. Using high-power laser cutting devices they created microscopic ‘spikes’ and ‘ridges’ in sheet metal, causing liquids to ‘bounce off’ the rough micro-topography that mimics the surface of the lotus leaf. The process is useful for medical cutting tools, sterile surfaces, dishwashers, or even saucepans…read more.
