Dragonflies: The Original NanotechNature’s physical solution to the superbug crisis

From the show

Nature Solved It First

Dragonfly wings offer a blueprint for defeating antibiotic-resistant bacteria through structural engineering rather than pharmaceuticals. Their surfaces contain microscopic pillars that physically tear bacterial walls apart on contact. Scientists are now applying this mechanical defense to medical implants and food packaging, creating self-sterilizing materials that do not rely on traditional drugs.
