摘要： Enveloped viruses encased within a lipid bilayer membrane are highly contagious and can cause many infectious diseases like influenza and COVID-19, thus calling for effective prevention and inactivation strategies. Here, we develop a diatomic iron nanozyme with lipoxidase-like (LOX-like) activity for the inactivation of enveloped virus. The diatomic iron sites can destruct the viral envelope via lipid peroxidation, thus displaying non-specific virucidal property. In contrast, natural LOX exhibits low antiviral performance, manifesting the advantage of nanozyme over the natural enzyme. Theoretical studies suggest that the Fe-O-Fe motif can match well the energy levels of Fe-2 minority beta-spin d orbitals and pentadiene moiety pi* orbitals, and thus significantly lower the activation barrier of cis,cis-1,4-pentadiene moiety in the vesicle membrane. We showcase that the diatomic iron nanozyme can be incorporated into air purifier to disinfect airborne flu virus. The present strategy promises a future application in comprehensive biosecurity control. Enveloped viruses encased within a lipid bilayer membrane are highly contagious and cause diseases like influenza and COVID-19, so strategies for their prevention and inactivation are needed. Here, the authors develop a diatomic iron nanozyme with lipoxidase-like activity for the inactivation of enveloped viruses, where the diatomic iron sites destroy the viral envelope via lipid peroxidation.
