A highly sensitive electrochemiluminescence biosensor for the detection of organophosphate pesticides based on cyclodextrin functionalized graphitic carbon nitride and enzyme inhibition.

A signal on an electrochemiluminescence (ECL) biosensor using β-cyclodextrin (CD) functionalized graphitic carbon nitride (g-C3N4) as the luminophore was constructed for sensitive organophosphate pesticides (OPs) detection based on the enzyme inhibition of OPs, showing that the consumption of coreactant triethylamine (Et3N) decreased with a lessening of the acetic acid (HAc) in situ generated by enzymatic reaction.
