Abstract
DNA hydrogels which are composed of an entangled network without a crosslinker are synthesized and examined in regards to their sensitivity to salt and pH changes. The DNA hydrogel fibers only exhibited a marked response – that is a fast and large change in length – under biological conditions ([Na+] = 0.15 m at pH = 7) and are therefore suitable materials for bio-inspired devices.
