Anti-bacterial surfaces inspired by cicada and dragonfly wings

dragon fly wings kill bacteria
This is the first reported example of a naturally existing surface with a physical structure that exhibits such effective bactericidal properties. Cicada wing nanopillars are extremely effective at killing Pseudomonas aeruginosa cells; the wing surface was able to kill individual cells within approximately 3 min. This bactericidal ability of the wing surface is primarily a physico-mechanical effect, as it is retained when the surface chemistry is substantially altered.
