A switchable electrode, which relies on an indium-tin oxide conductive substrate coated with a self-assembled monolayer terminated with an anthraquinone group (AQ), is reported as an electrowetting system. AQ electrochemical features confer the capability of yielding a significant modulation of surface wettability as high as 26° when its redox state is switched. Hence, an array of planar electrodes for droplets actuation is fabricated and integrated in a microfluidic device to perform mixing and dispensing on sub-nanoliter scale. Vehiculation of cells across microfluidic compartments is made possible by taking full advantage of surface electrowetting in culture medium.
据报道，一种可切换电极作为一种电润湿系统，它依赖于涂有以蒽醌基团（AQ）封端的自组装单分子层的氧化铟锡导电基底。AQ的电化学特性使其在氧化还原状态切换时能够产生高达26°的显著表面润湿性调制。因此，制造了一系列用于液滴驱动的平面电极，并将其集成到微流控装置中，以在亚纳升尺度上进行混合和分配。通过充分利用培养基中的表面电润湿，细胞跨微流控隔室的运输成为可能。
