Abstract
Clinical treatment of multidrug resistant (MDR) pathogens-induced infection is emerging as a growing challenge in global public health due to the limited selection of clinically available antibiotics. Nanozymes as artificial enzymes that mimicked natural enzyme-like activities, are received great attention for combating MDR pathogens. However, the relatively deficient catalytic activity in the infectious microenvironment and inability to precisely targeting pathogen restrains their clinical anti-MDR applications. Here, pathogen-targeting bimetallic BiPt nanozymes for nanocatalytic therapy against MDR pathogen are reported. Benefiting from electronic coordination effect, BiPt nanozymes exhibit dual-enzymatic activities, including peroxidase-mimic and oxidase-mimic activities. Moreover, the catalytic efficiency can be efficiently increased 300-fold by ultrasound under inflammatory microenvironment. Notably, BiPt nanozyme is further cloaked with a platelet-bacteria hybrid membrane (BiPt@HMVs), thus presenting excellent homing effect to infectious sites and precise homologous targeting to pathogen. By integrating accurate targeting with highly efficient catalytic, BiPt@HMVs can eliminate carbapenem-resistant Enterobacterales and methicillin-resistant Staphylococcus aureus in osteomyelitis rats model, muscle-infected mice model, and pneumonia mice model. The work provides an alternative strategy based on nanozymes for clinically addressing MDR bacteria-induced infections.
