Abstract
A fluorescence method was developed for selective detection of Ag<sup>+</sup> in the presence of Cd<sup>2+</sup>, Hg<sup>2+</sup>, and Cu<sup>2+</sup> based on gold nanoclusters. The limit of detection for Ag<sup>+</sup>, Hg<sup>2+</sup>, Cd<sup>2+</sup> and Cu<sup>2+</sup> is 1.19 μM, 3.39 μM, 1.83 μM and 5.95 μM, respectively.
