A highly selective cyanide sensing in water via fluorescence change and its application to in vivo imaging

Abstract

Among the various anions, only cyanide induced the revival of fluoresecence of 1-Cu2+ resulting in "Off-On" type sensing of cyanide, which can be monitored at pH 7.4 in 100% aqueous system, and has been applied to a microfluidic platform, in which fluorescent sensor 1-Cu2+ displayed green fluorescence upon the addition of cyanide, the in vivo imaging of cyanide using Caenorhabditis elegans. © 2009 The Royal Society of Chemistry.
