METAL-DISPERSED SCREEN-PRINTED CARBON ELECTRODES

Nickel-, cobalt-, copper-, and palladium-dispersed carbon inks are use d for screen printing of electrocatalytic sensors. The resulting strip s couple the advantages of mass-producible disposable electrodes and e ffective catalytic surfaces. The dispersed metal particles lead to a m arked decrease in the oxidation potential for carbohydrates, amino aci ds, aldehydes or alcohols. Characterization of the electrocatalytic be havior and the analytical (sensing) performance are reported. Applicab ility to wine samples is illustrated.
