Abstract:Dopamine (DA), a critical catecholamine in mammals, functions as a significant biological indicator for specific diseases. The precise and timely identification of DA is essential for disease monitoring and prevention. In this study, copper nanoclusters (Cu NCs) were synthesized using polyvinyl pyrrolidone (PVP) as the protective ligand and L‐ascorbic acid (L‐AA) as the reducing agent via a simple hydrothermal process. The produced PVP−Cu NCs displayed strong blue emission at 427 nm when excited at 365 nm. In … Show more
A novel PVP/4-MBA@Ni NCs fluorescent probe was developed for selective and sensitive detection of glutathione using ferric ion as an intermediate quencher.
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.
