We demonstrate a supramolecular approach to the fabrication of self-powered micropumps based on "host-guest" molecular recognition between α- and β-cyclodextrin and trans-azobenzene. Both hydrogels and surface coatings based on host-guest partners were used as scaffolds to devise the micropumps. These soft micropumps are dual stimuli-responsive and can be actuated either by light or by introducing guest molecules. Furthermore, the micropumps can be recharged through reversible host-guest interaction.
我们展示了一种基于α-和β-环糊精与反式偶氮苯之间“主客体”分子识别的自供电微泵的超分子制备方法。基于主客体配合物的水凝胶和表面涂层都被用作设计微泵的支架。这些软质微泵具有双重刺激响应性，可以通过光或引入客体分子来驱动。此外，通过可逆的主客体相互作用，微泵可以进行再充电。
