A simple, low-cost and label-free Hg(2+) ion sensor has been developed by using novel luminescent Ag(+) nanoclusters (NCs) with an excellent optical property (quantum yield = 15%), an ultra-high ratio of active Ag(+) species in the NC surface (100%), and an ultra-short diffusion path length of Hg(2+) ions to access the NC surface (0.5 nm).
一种简单、低成本且无需标记的 Hg(2+) 离子传感器已经被开发出来，它使用了具有优异光学性能（量子产率=15%）、超高比例的 NC 表面活性 Ag(+) 物种（100%）以及极短的 Hg(2+) 离子扩散路径长度（0.5nm）的新型荧光 Ag(+) 纳米团簇（NCs）。
