title: The Peculiar Response of DNA Hydrogel Fibers to a Salt and pH Stimulus.
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.
