Xanthine Oxidase: Disposable Biosensor for Herbal Antioxidant Evaluation

Abstract

The construction of a novel disposable Xanthine Oxidase (XOD) biosensor has been described Xanthine. Oxidase was physically entrapped with a biocompatible chitosan membrane. The sensor exhibits good performance in antioxidant capacity determination as the enzyme molecules experience less constraint with this immobilization method. The current decrease from the inhibition of the below reaction is utilize to determine the total antioxidant capacity for herbal quality assessment.
