英文摘要Enhancing the bactericidal properties of nanozymes and eliminating the need for H2O2 are crucial for biosafety and public hygiene. In this study, we introduce a novel thorned Ag4V2O7 nanorods for the first time, demonstrating their potential as oxidase-like and antibacterial agents. Due to their remarkable oxidase-like activity, Ag4V2O7 nanorods demonstrate potent bactericidal activity against both Escherichia coli, a representative Gramnegative bacterium, and Staphylococcus aureus, a prototypical Gram-positive bacterium, without the need for H2O2. The minimum inhibitory concentrations of Ag4V2O7 nanorods against Escherichia coli and Staphylococcus aureus are 0.78 and 1.56 mu g/mL, respectively, while their minimum bactericidal concentrations are also 1.56 and 3.12 mu g/mL. The bactericidal mechanism was investigated using electron paramagnetic resonance, radical trapping experiments and transmission electron microscopy analysis, which indicated that the Ag4V2O7 nanorods produce superoxide radicals to disrupt bacterial cell walls and membranes, leading to bacterial death. Notably, the nanorods maintained their antibacterial activity even after five bactericidal cycles, highlighting their stability and potential for practical applications in antimicrobial agents. Overall, our findings contribute to the advancement of medical science and environmental catalysis applications.
