DNA based ionophores can mediate efficient ion transport and are crucial to understand the biological role of their natural counterparts. Here authors engineer a telomeric DNA G-quadruplex based ionophore which transports K+ in a stimuli responsive m

Herein, we demonstrate for the first time that noncanonical DNA can direct macrocyclization-like challenging reactions to synthesize gene modulators. The planar G-quartets present in DNA G-quadruplexes (G4s) provide a size complementary reaction plat

Guanine-rich DNA sequences have the propensity to adopt four-stranded tetrahelical G-quadruplex (G4) structures that are overrepresented in gene promoters. The structural polymorphism and physicochemical properties of these non-Watson-Crick G4 struct

The selective transport of ions across cell membranes, controlled by membrane proteins, is critical for a living organism. DNA-based systems have emerged as promising artificial ion transporters. However, the development of stable and selective artif

We herein report the preparation of hydrogels by the Ag+ ion induced assembly of cytidine and boronic acids. These hydrogels, presumably formed by an i-motif like arrangement of cytidine and its bo...

Herein, we develop a competitive screening method in which G-quadruplex DNA linked magnetic nanoparticles pull down selective ligands for a particular quadruplex topology from a series of small molecules. The screening strategy is first optimized wit

G-quadruplexes (G4s) are guanine rich and i-motifs are cytosine rich non-canonical four-stranded DNA secondary structures present throughout the genome. Their presence in important regulatory regions of the genome marks their significance in biology.
