Combination of i‐Motif and G‐Quadruplex Structures within the Same Strand: Formation and Application

Abstract

Peaceful coexistence: A double quadruplex composed of an i-motif and a G-quadruplex was constructed within one oligonucleotide strand (see picture). The defined double-quadruplex structure can serve as a NOTIF logic gate on the basis of the fluorescence of crystal violet.
