Amperometric biosensors of food analysis relevance: Emphasis on the neurotoxin beta-ODAP in grass pea
Enzyme-based amperometric biosensors have been developed and characterized in flow systems for a variety of analytes such as [beta]-N-oxalyl-[alfa],[beta]-diamionpropionic acid ([beta]-ODAP), L-glutamate, glucose, lactate, and sucrose, that have food analysis relevance. The principle of enzyme "wiring" using polymeric mediators poly(1-vinylimidazole) {(Os-4, 4' dimethylbipyridyl)2Cl3+/2+} and poly
