Scheme 1

From: A resonance Rayleigh scattering sensor for sensitive differentiation of telomere DNA length and monitoring special motifs (G-quadruplex and i-motif) based on the Ag nanoclusters and NAND logic gate responding to chemical input signals

Scheme 1

Schematic illustration of structural conversion of the 1:1 mixture of G and C strands among duplex, quadruplex, and random coil forms as controlled by K+ and H+ (a duplex; b G-quadruplex and C random coil; c i-motif and G random coil; d G-quadruplex and i-motif)
