SENSOR SYSTEM FOR DETECTING ORGANOPHOSPHOROUS RESIDUES BY INDUCING COAGULATION OF GOLD NANOPARTICLES

摘要

The present invention relates to a sensor system for detecting organophosphorus pesticide residues using gold nanoparticles, imidazole or green fluorescent protein (GFP) and, more specifically, to an organophosphorus pesticides detection method which induces gold nanoparticles by reacting organophosphorus pesticides with imidazole or GFP, and accordingly uses a change in an absorption spectrum to detect organophosphorus pesticides. According to the present invention, a pesticide residue detecting system has a fast detection speed and an excellent optical change of a sample according to a presence of organophosphorus pesticides, and a range of a detection limit concentration is broad, so the invention can be useful for a pesticide residues biosensor for site analysis.
