Paper Abstract

A new method for the measurement of pesticide residues is described that utilizes an excited state photo-reaction in conjunction with a dehydrogenase enzyme based enzymatic reaction. The presence of the pesticide inhibits the enzymatic reaction, thereby affecting the production of the NADH. The latter co-factor undergoes an excited state photo- reduction, resulting in the NAD+ and photo-reduced form of the indicator fluorophore. The reported method is suitable for analyzing a number of pesticides, selectively. Various advantages, including the possibilities of using the assay in complex matrices, non-separation formats and cost- effectiveness, are discussed.
