Here for the first time, we present a novel electrochemiluminescence (ECL) sensor based on graphitic carbon nitride/graphene oxide (g-C3N4/GO) hybrid for the ultrasensitive detection of Cu2+, which is a common pollutant in environmental system. The g-C3N4/GO shows stable ECL signal in the presence of the self-produced coreactant from oxygen reduction, and the ECL signal could be effectively quenched...
In this paper, DNA functionalized single-wall carbon nanotubes/Cu 2+ (DNA–CNTs/Cu 2+ ) complex was one-step electrodeposited onto the glassy carbon electrode (GCE), which fabricated a DNA–CNTs/Cu 2+ /GCE sensor to detect nitrite. Cyclic voltammogram of DNA–CNTs/Cu 2+ /GCE showed a pair of well-defined redox peaks for Cu 2+ /Cu + . Compared with DNA–CNTs/GCE...
