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

Among the various anions, only cyanide induced the revival of fluoresecence of -Cu(2+) 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 -Cu(2+) displayed green fluorescence upon the addition of cyanide, the in vivo imaging of cyanide using Caenorhabditis elegans.
