  The mechanically induced melting properties of DNA were employed to achieve force labile membranes is described. Nucleobase pairs were used as mechanophores. Adenine and thymine functionalized complementary amphiphilic block copolymers were self-assembled into polymersomes. The nucleobases formed hydrogen bonds which were disrupted upon force stimulation. The exposure of the disconnected nucleobases to the hydrophobic matrix of the membranes lead to a change of permeability which permitted the exchange of water-soluble molecules throughout the polymer matrix. Moreover, the encapsulation of horseradish peroxidase enabled the reaction of luminol with hydrogen peroxide to yield a luminescence producing species similar to the marine bioluminescence. Moreover, the same nano-reactors were employed to catalyze the formation of a polyacrylamide gel when force was applied. Insights into the change of permeability of supramolecular networks upon force are provided. These systems are useful for drug delivery, as nanoreactors and for the selective release of curing agents for 3D printing, or fragrances.

  DNA的机械诱导熔化特性被用来实现易受力破裂的膜。核碱基对被用作机械感受器。腺嘌呤和胸腺嘧啶功能化的互补两性分块共聚物自组装成聚合体囊。核碱基形成氢键，在受力刺激下被破坏。断开的核碱基暴露在膜的疏水基质中，导致渗透性的改变，从而允许水溶性分子在聚合物基质中交换。此外，封装辣根过氧化物酶使得辣根酰胺与过氧化氢反应产生类似海洋生物发光的发光物种。此外，当施加力时，相同的纳米反应器被用来催化聚丙烯酰胺凝胶的形成。提供了关于受力下超分子网络渗透性变化的见解。这些系统可用于药物传递、纳米反应器以及用于3D打印的固化剂或香料的选择性释放。
