   Abstract : 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(4-vinlypyridine {Os(N,N'-dimethyl-2,2'-biimidazole)3}3+/2+ has been employed in most of the sensors developed, which resulted in the fabrication of sensitive, stable and reproducible biosensors with carbonaceous electrodes (spectrographic graphite and glassy carbon).
