Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics
Advanced Functional Materials, EarlyView.Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...
