Just Add Water: DNA Hydrogel Remembers Its Original Shape When Resubmerged
A new DNA-based hydrogel collapses into a liquidlike puddle when taken out of water and regains its original shape when plunged back in, according to a report in Nature Nanotechnology (DOI: 10.1038/nnano.2012.211). Although the researchers who discovered the unique material aren’t yet sure why it’s capable of such a feat, they think it could eventually be used for drug delivery and in electrical switches and robotics.. . .
