Abstract
The present invention relates to a new antioxidant sensor based on metallic or metallic oxide modified electrode and its associated method for electrochemically generating hydroxyl radicals and their subsequent use for the electrochemical measurement of antioxidant activities based on hydroxyl radical scavenging properties of the tested sample.
Claims17
An electrode used for determining the hydroxyl radical scavenging properties of antioxidants in an aqueous solution comprising a catalyst able to generate hydroxyl radicals during a cathodic polarisation in an aqueous solution containing hydrogen peroxide or dissolved oxygen, and yielding a catalytic current sensitive to the presence of antioxidants in the solution.
