The Enhanced Photocatalytic Sterilization of a Metal-Organic-Framework-Based S-Scheme Heterostructure of Ag₂S@PB for Rapid Healing of Bacteria-Infected Open Wounds.

ABSTRACT: Developing new photocatalytic materials is one of the most promising strategies to address bacterial infection during wound healing without bacterial drug resistance, but their poor photocatalytic activity ultimately limits their therapeutic efficacy. In this work, a metal-organic framework-based S-scheme heterostructure (Ag₂S@PB) is prepared to rapidly treat open wounds caused by bacterial infection, which effectively establishes and retains spatially isolated redox centers through an S-scheme charge-transfer pathway. Additionally, the formation of an interface electric field and covalent Fe-S bridge bonding in the heterogeneous interface endows the heterojunction with a much stronger charge separation and transfer capability than bare Ag₂S, which significantly enhan
