A disposable monoenzymatic sensor for the reliable determination of dithiocarbamate fungicides was developed based on aldehyde dehydrogenase inhibition. Aldehyde dehydrogenase was immobilized on the surface of a disposable screen-printed carbon-paste electrode by using a photocross linkable poly-(vinylalcohol) bearing styrylpyridinium groups. Electrochemical oxidation of NADH was carried out at a potential as low as 0V vs Ag/AgCl using Meldola's

Screen-printed electrodes coupled with appropriate mediators were used as transducers for this novel biosensor. MQO was immobilized by physical entrapment in a photo-cross-linkable poly(vinyl alcohol) polymer (PVA-SbQ) on the surface of the working electrode. Several electrochemical mediators were studied in
