DNA hydrogels, consisting of Y-shaped nucleic acid subunits or of nucleic acid-functionalized acrylamide chains, undergo switchable gel-to-solution transitions. The Ag(+)-stimulated formation of cytosine-Ag(+)-cytosine complexes results in the crosslinking of the units to yield the hydrogels, while the cysteamine-induced elimination of the Ag(+) ions dissociates the hydrogels into a solution phase.
DNA 水凝胶由 Y 型核酸亚基或核酸功能化丙烯酰胺链组成，经历可切换的凝胶到溶液的转变。Ag(+) 刺激胞嘧啶-Ag(+)胞嘧啶复合物的形成导致单元交联以生成水凝胶，而半胱胺诱导的 Ag(+) 离子消除则将水凝胶解离到溶液相中。
