title: Highly sensitive turn-on detection of Ag+ in aqueous solution and live cells with a symmetric fluorescent peptide.
abstract: This communication presents a symmetric fluorescent peptide (K(d) = 17.4 nM) for hypersensitively detecting Ag(+) in 100% aqueous solution by turn-on response. The peptide penetrated live HeLa cells and detected intracellular Ag(+) by turn-on response.
