title: G-quadruplex signaling probe for highly sensitive DNA detection.
abstract: Ferrocene-conjugated oligonucleotides that can form intermolecular guanine (G)-quadruplexes are prepared and used as signaling probes for detecting target DNA, improving substantially assay characteristics (e.g. a considerably wider linear dynamic range and lower detection limit).
