摘要:
Pesticide sensing crucially safeguards food safety and public health against environmental and health hazards. While oxidoreductase-type nanozymes (peroxidase and oxidase) have been widely used in optical pesticide detection, their susceptibility to redox interference as well as poor target specificity limits practical applications. To overcome the deficiencies, here we developed Ca 2+ -chelated 2-aminoterephthalic acid on nanosized ceria (Ca-ATPA@CeO 2 ) as an organophosphorus hydrolase mimic. This design integrates stable fluorescence and dua...
