Environmentally Responsive Catalytic Microneedles Enable Cascade Fenton Reaction for Antibacterial Therapy and Accelerated Infected Wound Healing.
The persistence of bacterial biofilms and resistance limits the efficacy of traditional therapies, slowing tissue regeneration. Here, we report an innovative pH-responsive catalytic microneedle system (GZIF@Fe MN) designed to combat bacterial infections by disrupting bacterial redox homeostasis through a cascade Fenton...
