“…Nanozymes, i.e nanomaterials with natural enzyme-mimetic catalytic performances, have inspired extensive applications in biomarker detection [13], cancer diagnosis and therapy [14], biosensing [15], and food analysis due to their low cost, high stability, easy storage, tunable catalytic activities, and easy functional modi cation compared with natural enzymes [16,17]. Since Yan et al rst reported magnetite (Fe 3 O 4 ) NPs have catalytic reaction kinetics and catalytic mechanisms similar to those of natural horseradish peroxidase [18], many nanomaterials with different compositions also have such enzymatic properties been developed [19,20]. Recently, nanozymes have emerged as new tools to defeat bacterial infection, and the potential of nanozymes has drawn more and more attention in antibacterial applications [21][22][23].…”
