An Electrochemiluminescence Immunosensor for Determination of Methsulfuron-methyl

Abstract

Abstract: An electrochemiluminescence(ECL) biosensor based on solid-phase antigen competitive immunoreactions was constructed to determine methsulfuron-methyl using Ru(bpy)₃²⁺ as labeling reagent. The coating hapten was bound to the surface of microparticles through avitin-biotin reaction. An electrochemical flow cell containing working electrodes and counter electrodes for initiation of the ECLreaction was constructed. Results showed that the detection limit for methsulfuron-methyl was 0.1 ng/mL.

Key words: Electrochemiluminescence, Immunosensor, Methsulfuron-methyl
