The activities of praseodymia mimicking both oxidase and peroxidase were examined which led to excellent oxidative capacity in generating species such as holes and hydroxyl radicals. The antibacterial performance of praseodymia nanorods from precipitation method was investigated in comparison with commercial samples. Incubation of praseodymia with E. Coli results in significant reduction of bacterial proliferation in both swarming and inhibition experiments, but not with S. aureus. This could potentially provide a new bactericidal strategy to combat abiotic or strain-selective drug resistance in future applications. 收起
