Abstract
A new method using cheap homemade dual-electrodes has been developed to measure the antioxidant capacity of phenolic compounds. These micro-sized electrodes are elaborated by successive screen-printing of conductive ink and insulator layers and are then used as generator/collector sensors. Cyclic voltammetry and chronoamperometry with a bipotentiostat have been used to test and characterize these sensors. The antioxidant capacity values found by this new method are compared with a classical method (using a macro-sized electrode) to demonstrate its reliability.Keywords
