Microfluidic paper-based chip for parathion-methyl detection based on a double catalytic amplification strategy

The rapid detection of insecticides such as parathion-methyl (PM) requires methods with high sensitivities and selectivities. Herein, a dual catalytic amplification strategy was developed using Fe 3 O 4 nanozyme-supported carbon quantum dots and silver terephthalate metal–organic frameworks (Fe 3 O...
