Preparation and characterization of COOH-G/Au@Ag nanocomposites and its electrogenerated chemiluminescence sensing for glucose

An electrochemiluminescence (ECL) sensor was developed with carboxylated graphene-loaded [email protected] core-shell nanoparticles. Scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM) and inductive coupling plasma (ICP) were applied to characterizing COOH-G/[email protected] nanocomposites. Electrochemical performance of the nanocomposites was evaluated by cyclic voltammetry...
