Insect wing structure kills some bacteria; biomimicry could help clean some surfaces
The nanoscale hexagonal structure of the clanger cicada's
wings kills some bacteria on contact by straining and rupturing the bacterial
cell. The study hints that infection control could be improved by replicating
the wing's structure many surfaces and on germ-laden public facilities such as hand rails.
