建立了一种在水介质中使用荧光金纳米管检测Hg2+离子的简便、高选择性和高灵敏度的无标记方法。该传感机制基于高亲和的亲金属Hg2+-Au+相互作用，该相互作用有效地猝灭了Au NCs的荧光。
A simple label-free method for the detection of Hg2+ ions with high selectivity and sensitivity has been developed by using fluorescent Au NCs in aqueous media. The sensing mechanism was based on the high-affinity metallophilic Hg2+-Au+ interactions, which effectively quenched the fluorescence of Au NCs.
