我们报道了一种新的脂质双层系统，在该系统中，除了传统的跨膜电压外，还可以施加横向偏压。在微孔中形成了掺杂[6，6]-苯基-C-61-丁酸甲酯(PCBM)的独立双层脂膜(BLM)，并在其周围沉积了金属电极。使用该系统，可以通过沿BLM施加横向偏置来调制和放大光诱导的跨膜电流。结果表明，埋入电极的微细硅片是形成基于PCBM掺杂BLM的类晶体管器件的良好平台，具有广泛的应用前景。
We report on a novel lipid bilayer system, in which a lateral bias can be applied in addition to a conventional transmembrane voltage. Freestanding bilayer lipid membranes (BLMs) doped with [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM) were formed in a microaperture, around which metal electrodes were deposited. Using this system, it was possible to modulate and amplify photoinduced transmembrane currents by applying a lateral bias along the BLM. The results indicate that the microfabricated Si chip with embedded electrodes is a promising platform for the formation of transistor-like devices based on PCBM-doped BLMs and have potential for use in a wide variety of nanohybrid devices.
