An internal charge transfer-DNA platform for fluorescence sensing of divalent metal ions

Chem Commun (Camb). 2016 Jul 21;52(61):9586-8. doi: 10.1039/c6cc04613d.

Abstract

Replacement of guanine (G) nucleobases within G-quadruplex (GQ) folding oligonucleotides with push-pull fluorescent 8-arylvinyl-dG residues provides diagnostic emission signalling for divalent metal ion binding.
