Abstract
In this paper, we prepared Au nanoclusters through chemical reduction method. The nanoclusters were stabilized by biological macromolecular bovine serum albumin. High resolution transmission electron microscopy (TEM) showed that BSA coating fluorescent Au clusters nanoparticles dispersion was good, no obvious aggregation, uniform particle size, during this process, we changed the reaction conditions of time and pH and researched the influence of their fluorescent intensities. Further, we continued to adjust reaction conditions for the detection of Hg2+. In the detection process, we changed the concentration of Hg2+, achieve to the intelligent detection of Hg2+. Then, we introduced other metal ions to this system and tested the selective detection of Hg2+. At last, we researched the action mechanism between Au nanoclusters and Hg2+.
