Highly selective fluorescence turn-on sensing of gold ions by a nanoparticle generation/C-I bond cleavage sequence

Analyst. 2012 Oct 7;137(19):4411-4. doi: 10.1039/c2an35351b.

Abstract

We have developed a quickly responsive, and specific fluorescent assay for the detection of Au(III) on the basis of the formation of gold nanoparticles in the presence of HEPES, which cleave the C-I bond of I-BODIPY 1 to yield the highly fluorescent H-BODIPY 2.
