H2O2/Acid Self-Supplying Double-Layer Electrospun Nanofibers based on ZnO2 and Fe3O4 nanoparticles for Efficient Catalytic Therapy of Wound Infection

Catalytic therapy based on nanozymes is promising for the treatment of bacterial infections. However, its therapeutic efficacy is usually restricted by the limited amount of hydrogen peroxide and the weak acidic environment in infected tissues. To solve these issues, we prepared polyvinyl alcohol (PVA)-polyacrylic acid (PAA)-iron oxide (Fe
