Abstract
A sensor system detects organophosphorus pesticide residue by inducing the aggregation of gold nanoparticles. A method comprises aggregating gold nanoparticles by a reaction between an organophosphorus pesticide and imidazole or a green fluorescent protein (GFP), and detecting the organophosphorus pesticide based on a absorption spectral change resulting from the aggregation. The system for detecting pesticide residue is useful as a biosensor for analyzing pesticide residue in situ, because the optical change of the reagent by the presence of an organophosphorus pesticide is distinct, the detection speed is fast, and the range of detection limits is broad.
