Amperometric Enzyme Carbon Paste-Based Biosensor for Quantification of Hydroquinone and Polyphenolic Antioxidant Capacity

An amperometric biosensor for the determination of hydroquinone and other polyphenolic antioxidants is presented, based on a carbon paste electrode on which tyrosinase is immobilized in a Nafion® film. In a 0.1 M phosphate buffer (pH 7.0 and 25 º 1 °C), the antioxidant capacity can be expressed as t...
