A bifunctionalized NiCo2O4-Au composite: Intrinsic peroxidase and oxidase catalytic activities for killing bacteria and disinfecting wound
Abstract
A recyclable NiCo2O4-Au composite was fabricated. The integration of Au with NiCo2O4 provided peroxidase- and oxidase-like activities. NiCo2O4-Au could effectively kill bacteria and destruct biofilms with 100 μM H2O2. NiCo2O4-Au based Band-Aid exhibited high anti-infective and wound-healing efficiency. The antibacterial mechanism was the formation of OH and 1O2.
