Electrochemical recognition based on Au@nitrogen-doped carbon quantum dots@Ag core-shell (Au NPs@NCDS@Ag NPs) composite including molecular imprinted polymer (MIP) was presented for metobromuron (MBN) detection. Firstly, novel triple-layered core-shell structure including gold nanoparticles core, nitrogen-doped carbon quantum dots interlayer and silver nanoparticles outside shell was synthesized by the reduction of chloroauric acid (HAuCl4), silver nitrate (AgNO3) in the presence of NCDS. Secondly, MBN imprinted polymer on Au NPs@NCDS@Ag NPs composite was electrochemically performed in the presence of pyrrole and MBN via cyclic voltammetry (CV). Fourier-transform infrared spectroscopy (FTIR), transmission electron microscope (TEM), energy-dispersive x-ray (EDX) spectroscopy, x-ray diffraction (XRD) method and electroanalytical methods such as CV, chronoamperometry (CA), electrochemical impedance spectroscopy (EIS) were performed for characterizations of core-shell structure. MBN imprinted electrode showed high electrocatalytic performance and the linear range of 1.0 x 10(-12)-2.0 x 10(-9) M and detection limit (LOD) of 2.0 x 10(-13) M were obtained.
