摘要：

Gold-chitosan nanocomposite is successfully proposed for assembling a sensitive and selective electrochemical sensor for the determination of an antioxidant such as caffeic acid, which has recently attracted much attention due to its benefits on human health. In this paper, taking advantage of the peculiar sensing performance of the nanocomposite, an analytical method based on differential pulse voltammetry for determination of polyphenol index in wines was proposed.
