An anti-galvanic reduction single-molecule fluorescent probe for detection of Cu(ii)†
Abstract
An anti-galvanic reduction method using [Ag62S13(SBut)32]4+ nanoclusters as the metal ion probe for detecting Cu2+ is reported here. We found [Ag62S13(SBut)32]4+ can reduce more reactive Cu2+ with a quantitative relationship. The single molecule fluorescence imaging shows that Ag62 NCs could be used as a single molecule probe for detecting Cu2+.
