A novel fluorescence probing strategy for the determination of parathion-methyl.

Abstract

A sensitive fluorescence probing strategy for parathion-methyl (PM) detection was developed based on electron transfer (ET) between p-nitrophenol (the hydrolysate of PM) and CdTe quantum dots (QDs) in cetyltrimethylammonium bromide (CTAB). PM was hydrolyzed by organophosphorus hydrolase (OPH) to form p-nitrophenol. P-nitrophenol is a typically electron… (More)
