Screen-printed enzyme electrodes for the detection of marker analytes during winemaking

, : Screen-printed enzyme electrodes for the detection of marker analytes during winemaking. Analytica Chimica Acta 513(1): 67-72

Biosensors for malic acid and glucose were developed, using screen-printed electrodes and 2 different classes of enzymes: NAD(P)+-dependent dehydrogenases and oxidases. The active surface of the electrodes was modified using Meldola Blue (malic acid) and Prussian Blue (glucose) and in this way sensitive, low cost and reliable NAD(P)H and H<sub>2</sub>O<sub>2</sub> probes were obtained. Fixed potential amperometry was used for the detection of substrates in small volumes of sample (50 micro l).
