Abstract:
We introduce a one-pot synthesis strategy to prepare fluorescent Au nanodots (AuNDs) for highly sensitive and selective Mercury (II) ions (Hg2+) detection in aqueous solution. The sensing mechanism is attributed to strong metal-metal interactions between Hg2+ and Au+ induced fluorescence quenching of AuNDs. The limit of detection (LOD, S/N = 3) is 0.1 nM for Hg2+.
