Abstract:Due to poor electro-active and less structural differences of glucocorticoids, it is still a challenge to realize simultaneous electrochemical detection of different glucocorticoids in wastewater. Here an electrochemical biosensing platform was constructed through electrochemical in situ polymerization. A poly(sulphosalicylic acid) (PSSA) composite electrode was prepared based on polymerized L-arginine (Arg) doped with carbon quantum dots (QDs) and GCE-Arg-PSSA-QD sensor was obtained. Transmission electron mic… 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.
