A pH‐Triggered, Fast‐Responding DNA Hydrogel

Abstract

Y switch? A fast, pH-responsive DNA hydrogel (see picture; right) was prepared by a three-armed DNA nanostructure (left) assembling together through the formation of intermolecular i-motif structures (middle). The hydrogel can be switched to the non-gel state in minutes by simply using environmental pH changes. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
