An overview of the use of nanozymes in antibacterial applications

Topics of bacterial resistance have attracted remarkable scientific interests. Bacterial infection-related diseases are major public safety issues that lead to millions of deaths annually. Therefore, it is urgent to develop novel, high efficiency, and bacteria-binding antibacterial agents. As far as now, the emergence of nanozymes has been presented as promising candidates to combat bacteria. Combining the advantages of nanomaterials and natural enzymes, such nanozymes are generally low cost, good stability, controllable size, easy-of-preparation, multifunctionality, and superior catalytic activity. As the potent antibacterial agents, nanozymes possess satisfying broad-spectrum antibacterial abilities and biocompatibility. Herein, we timely summarize the recent research progress of different kinds of nanozyme-based antibacterial agents. Additionally, the relevant antibacterial mechanisms of nanozymes and the roles of physicochemical properties, external stimuli, and surface modifications on their catalytic performances and biosafety are also discussed. Finally, current challenges and the future perspectives are covered to stimulate new strategies and more effective nanozyme-based antibacterial agents for preclinical translations.
