A direct and fast voltammetric method of determination of 2,8-dihydroxyadenine (2,8-DHA), with a novel nanostructured carbon fiber sensor (CFS), is revealed in this work. To achieve high sensitivity required in biological determinations, before the determination of 2,8-DHA, carbon fiber sensors were activated by electrochemical pretreatment method. The electrochemical activation process generates a nanostructured carbon fiber surface, which is stable. The high stability of the active surface, and the high rep…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
