Scientists are replicating the antibacterial and self-cleaning properties of cicada wings for medical applications. Researchers found that cicada wings’ nanostructures, called nanopillars, kill bacteria by stretching and rupturing their cell membranes. Using directed self-assembly techniques, synthetic nanopillars were created from polystyrene and coated with titanium oxide, proving effective against bacteria like E. coli and Listeria. This innovation could lead to medical devices that both kill and clean bacteria, enhancing patient safety.
