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 ...

Anaesthesia, 1967 SUMMARY A case is described where a metal nozzle from a lignocaine spray bottle became detached at laryngoscopy, passing unnoticed into the pharynx and oesophagus. It was subsequently recovered at laparotomy from the patient's large bowel where its further progress had been arrested by an obstruction at this site.
