In a new study, researchers describe how the veined wing of the Clanger cicada is the first known example of a natural biomaterial that kills bacteria on contact, using only its physical structure, unaided by chemical or biological agents. Tiny nanopatterns on the locust-like insect's wing surface simply tear the microorganisms apart. By studying such physical properties researchers hope to spur the design of new antibacterial materials that can be used on handrails and similar frequently-touched surfaces.
