Since they are flexible, high-aspect-ratio nanostructures store elastic energy. When released, this energy could be used to destroy bacteria by physically stretching and rupturing their cell membranes. This technique was inspired by the bactericidal nature of insect wings and destroys both Gram-positive and Gram-negative bacteria at extremely high rates. The nanostructures could make for a new type of highly efficient mechano-responsive antibacterial surface.
