The authors report that the fluorescence of polymer-capped silver nanoclusters (AgNCs) is quenched by MoS2 nanosheets. However, in the presence of electrolytes such as sodium acetate (50 mM), the nanosheets tend to aggregate, and this causes fluorescence to be restored. If, however, ssDNA is added, it will be adsorbed on the surface of the MoS2 nanosheets and stabilize them against aggregation. As...
Palladium modified cerium oxide (CeO 2 or ceria) nanoparticles (Pd-CeO 2 ) were prepared by depositing palladium nanoparticles with average diameters of 3–5nm on the surface of CeO 2 via chemical reduction of the precursor (Pd 2+ ). The electrocatalytic activity of Pd-CeO 2 toward the detection of different important compounds (i.e. glucose, ascorbic acid (AA),...
