Controlling Wettability: 'Sticky tape' for Water Droplets Mimics Rose Petal | Biomimicry |

A new nanostructured material may lead to surfaces that stay dry forever, never need cleaning and are able to repel bacteria and even prevent mold and fungi growth. "The newly discovered material uses raspberry particles -- so-called because of their appearance -- which can trap tiny water droplets and prevent them from rolling off surfaces, even when that surface is turned upside down," said Dr Andrew Telford from the University's School of Chemistry and lead author of the research recently published in the journal, Chemistry of Materials. The raspberry particles mimic the surface structure of some rose petals.
