Graphene kills harmful bacteria “superbugs” but spares human cells

Scientists have uncovered how graphene oxide pulls off a remarkable trick: it hunts down and destroys harmful bacteria while leaving human cells completely unharmed. By targeting a molecule found only in bacterial membranes, this ultra-thin carbon-based material acts with laser-like precision—offering a powerful new alternative to traditional antibiotics. Even more exciting, it works against drug-resistant “superbugs,” promotes faster wound healing, and keeps its antibacterial strength even afte...
