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