H 2 O 2 /acid self-supplying double-layer electrospun nanofibers based on ZnO 2 and Fe 3 O 4 nanoparticles for efficient catalytic therapy of wound infection

by 3.1 log (99.92%). Moreover, PPF/PZ NFs can efficiently treat the bacterial infection in a mouse wound model and promote wound healing with negligible toxicity to animals, indicating their potential use as "plug-and-play" antibacterial wound dressings. This work provides a novel strategy for the construction of double-layer electrospun nanofibers as catalytic wound dressings with hydrogen peroxide/acid self-supplying properties for the efficient treatment of bacterial infections.
