Simple-synthesis VO₂ nanoparticles as robust nanozymes for synergistic antibacterial therapy and abscess repair.

ABSTRACT: Multidrug resistant (MDR) bacterial infections, particularly those involving methicillin-resistant Staphylococcus aureus (MRSA), pose a grave threat to global population health, necessitating novel therapeutic approaches capable of circumventing existing resistance mechanisms. Biomimetic enzymes, which generate bactericidal reactive oxygen species (ROS) by mimicking natural enzyme activity, represent a highly promising solution. This study reports a straightforward one-step synthesis method for vanadium dioxide (VO₂) nanoparticles, which function as potent biomimetic enzymes exhibiting both oxidase-like and peroxidase-like activities. When combined with near-infrared laser irradiation (808 nm, 1 W/cm²) for photothermal therapy (PTT), these VO₂ nanoparticles not only mediate local hyperther
