An ultratrace assay of arsenite based on the synergistic quenching effect of Ru(bpy) 3 2+ and arsenite on the electrochemiluminescence of Au-g-C 3 N 4 nanosheets
A novel ratiometric electrochemiluminescence (ECL) indicator has been constructed for ultratrace As(iii) detection based on the synergistic quenching of ECL emission of Au-g-C3N4 NSs using As(iii) and Ru(bpy)32+, meanwhile generating a new ECL signal of Ru(bpy)32+ with an increased intensity. Due to...

Summary: | A novel ratiometric electrochemiluminescence (ECL) indicator has been constructed for ultratrace As(iii) detection based on the synergistic quenching of ECL emission of Au-g-C3N4 NSs using As(iii) and Ru(bpy)32+, meanwhile generating a new ECL signal of Ru(bpy)32+ with an increased intensity. Due to the dual quenching effect of As(iii) and Ru(bpy)32+ coupled with the generation of the second ECL signal of Ru(bpy)32+, the sensitivity and selectivity for detecting As(iii) are vastly enhanced. |
