| Popis: | Reconfigurable DNA structures DNA origami—nanostructures created by programming the assembly of single-stranded DNA through base pairing—can create intricate structures. However, such structures lack the flexible and reversible interactions more typical of biomolecular recognition. Gerling et al. created three-dimensional DNA nanostructures that assemble though nucleotide base-stacking interactions (see the Perspective by Shih). These structures cycled from open to closed states with changes in salt concentration or temperature. Science, this issue p. 1446 ; see also p. 1417 |
