Silver nanoclusters as fluorescent probes for selective and sensitive detection of copper ions

Fluorescent DNA-Ag NCs are demonstrated as novel, label-free, and turn-on fluorescence probes for Cu(2+) ions sensors. We also used this novel fluorescent probe to determine Cu(2+) ions in Montana soil (SRM 2710) and pond water.
