Tiny structures show big antibacterial potential

Black silicon, silicon that has been etched with tiny bumps called nanoprotrusions, may be an effective bacteria killer.

A new study observed that similarly textured nanostructures in the wings of cicadas and dragonflies efficiently and effectively shred rod-shaped bacteria.

This finding could lead to the development of nanomaterial coatings for medical implants to make them safer against dangerous bacteria.
