Electrochemistry as a Tool for Studying Antioxidant Properties

Electrochemical methods provide high potential for investigation of antioxidant compounds, assessment of antioxidant capacity, and measurement of electrochemical index. Different types of electrodes can be used for the assay purposes. The devices can be stationary or flow through, and based on cyclic or differential pulse voltammetry as well as potentiostatic analysis. The methods are known for their suitability for food control and monitoring the levels of antioxidant capacity in other biological samples and matrices. In this review, the application of both stationary and flow electrochemical methods for analysis of plant and clinical samples with respect to study of their antioxidant properties is described. The advantages and disadvantages of the methods are discussed.
