Metal-dispersed screen-printed carbon electrodes

Nickel-, cobalt-, copper-, and palladium-dispersed carbon inks are used for screen printing of electrocatalytic sensors. The resulting strips couple the advantages of mass-producible disposable electrodes and effective catalytic surfaces. The dispersed metal particles lead to a marked decrease in the oxidation potential for carbohydrates, amino acids, aldehydes or alcohols. Characterization of the electrocatalytic behavior and the analytical (sensing) performance are reported. Applicability to wine samples is illustrated.
