Abstract:A novel electrochemical sensor based on a hybrid of single-walled carbon nanotube and nanoparticle modified glassy carbon electrode was prepared by using mechanical attachment technique. The nanocomposite immobilized on the surface of a glassy carbon electrode offers substantial enhancement in the sensitivity and lower detection limit for the electrochemical determination of ascorbic acid. Voltammetric characterization indicated that the anodic peak current increased about 3.5 times in comparison with the bare… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
