Nanozymes with peroxidase-like activity have great application potential in combating pathogenic bacterial infections and are expected to become an alternative antibiotics. However, the near-neutral pH high glutathione (GSH) levels infection microenvironment severely limit their applications antibacterial therapy. In this work, a metal–organic framework (MOF)-based cascade catalytic glutathione-depleting system named MnFe2O4@MIL/Au&GOx (MMAG) was constructed. The MMAG cascade-catalyzed glucose provide H+ produces large amount of toxic reactive oxygen species. addition, consumed GSH, which can result death more easily. Systematic experiments illustrated that has superior effects on both Gram-positive bacteria Gram-negative bacteria.
