title: Reversible regulation of the supramolecular chirality of a cyanine dye by using the G-quadruplex structure as a template.
abstract: Multiple cycle regulation of the supramolecular chirality of a cyanine dye has been successfully achieved by using DNA G-quadruplexes as templates, which is easily controllable by repeated addition of Ag(+) and cysteine (Cys). This work provides an easy and controllable strategy for the chiral regulation of supramolecules.
