A new fluorescence probing strategy for the detection of parathion-methyl based on N-doped carbon dots and methyl parathion hydrolase

A novel system made up of nitrogen doped carbon dots (NCDs) and methyl parathion hydrolase (MPH) was developed for the detection of parathion-methyl (PM). This method is based on inner filter effect (IFE) and molecular interactions between NCDs and p-nitrophenol, which is the hydrolysis product of PM catalyzed by MPH.
