Abstract:Salicylic acid (SA) is effective in the treatment of coronary heart disease. In this study, a novel PEC sensor was prepared to specifically detect SA, and copper sulfide-layered double hydroxide/reduced graphene oxide (CuS-LDH/rGO) with visible light activity was chosen as the identification element and photoactive material. The photocurrent response of CuS-LDH/rGO shows linear relationship with SA concentration over a range of 1–80 μM and 160–5760 μM, with a low limit of detection (LOD) (S/N=3) of 0.35 μM. Th… 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.
