Abstract(s)
To counteract and prevent the deleterious effect of free radicals the living organisms have developed
complex endogenous and exogenous antioxidant systems. Several analytical methodologies have been
proposed in order to quantify antioxidants in food, beverages and biological fluids. This paper revises the
electroanalytical approaches developed for the assessment of the total or individual antioxidant capacity.
Four electrochemical sensing approaches have been identified, based on the direct electrochemical
detection of antioxidant at bare or chemically modified electrodes, and using enzymatic and DNA-based
biosensors.
