A glassy carbon electrode was modified with an array of porous Ni3N nanosheets (Ni3N NA) and studied for its use in non-enzymatic electrochemical detection of glucose. The morphology and structure of the Ni3N NA were characterized by scanning electron microscopy and X-ray diffraction. Electrochemical studies demonstrated that the Ni3N NA acts as an efficient catalyst for the electro-oxidation of glucose...
Silver nanoclusters (Ag NCs) were synthesized based on dC12 strands as template. The fluorescence intensity of the Ag NCs was found to be pH dependent and pH reversible, that is, the fluorescence intensity was quenched with the decrease of pH and can be recovered to exact value again with the adjustment of pH value to neutral. This pH dependent fluorescence property was utilized for the sensitive...
