二氯甲烷通过涂覆有十二烷基苯磺酸盐掺杂的聚吡咯的铂网的受控运输和递送被证明在原位电化学氧化还原开关后。由于表面活性剂掺杂剂释放到二氯甲烷中以及聚合物表面能的变化，在聚合物还原时，观察到二氯甲烷液滴自由地穿过网。平面和液体填充管配置进行了研究。这些概念被设想为证明可用于微流体装置中的流体控制、用于药物递送的微粒的制备以及有机微反应器的开发。
The controlled transport and delivery of dichloromethane through platinum mesh coated with dodecylbenzenesulfonate-doped polypyrrole is demonstrated upon in situ electrochemical redox switching. Droplets of dichloromethane were observed to pass freely through the mesh upon reduction of the polymer as a result of the release of the surfactant dopant into the dichloromethane and the change in the surface energy of the polymer. Planar and liquid-filled tube configurations are investigated. These concepts are envisaged to prove useful for fluid control in microfluidic devices, in the preparation of microparticles for drug delivery, and in the development of organic microreactors.
