摘要：

(Figure Presented) Nucleic acid-functionalized polyacrylamide chains that are cooperatively cross-linked by i-motif and nucleic acid duplex units yield, at pH 5.0, DNA hydrogels exhibiting shape-memory properties. Separation of the i-motif units at pH 8.0 dissolves the hydrogel into a quasi-liquid phase. The residual duplex units provide, however, a memory code in the quasi-liquid allowing the regeneration of the hydrogel shape at pH 5.0. © 2014 Wiley-VCH Verlag GmbH & Co. KGaA.
