Cicada and safe surfaces

Bye-bye bacteria! How an insect’s wings inspired materials that could keep surfaces free from bacterial infections.

Replicating this remarkable design could lead to the development of antibacterial materials with potential for industrial and medical use. Thanks for listening.
