Abstract
We have developed a strategy for the ratiometric detection of toxic Hg(2+) ions using a semiconductor nanocrystal energy-transfer donor coupled to a mercury-sensitive "turn-on" dye acceptor. The results demonstrate a new paradigm of toxic metal sensing that resolves the difficulties with the use of semiconductor nanotechnology for this purpose.
摘要
我们开发了一种比率型检测有毒 Hg(2+)离子的策略，该策略使用半导体纳米晶能量转移供体与汞敏“开启”染料受体相偶联。研究结果展示了一种有毒金属感应的新范例，解决了半导体纳米技术在这方面应用的难题。
