Development of a disposable biosensor for the detection of metham sodium and its metabolite MITC
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
