Role of Copper Oxides in Contact Killing of Bacteria
The potential of metallic copper as an intrinsically antibacterial material is gaining increasing attention in the face of the growing antibiotic resistance of bacteria. However, the mechanism of the so-called "contact killing" of bacteria by copper surfaces is poorly understood and requires further investigation. In particular, the influences of bacteria–metal interaction, media composition, and copper surface chemistry on contact killing are not fully understood. In this study, copper oxide fo
