离子转运在正常的身体功能中尤其重要，其由专门的离子通道调节。本文在液/液（L/L）界面构建简单的亲水性氧化铝纳米通道，模拟生物系统在类似生理盐水环境中复杂的跨通道离子转移过程。由于氧化铝纳米通道的电表面性质可控，实现了离子通道的选择性和调节性这两个重要特性。该通道对低电负性离子具有良好的选择性。通过改变纳米通道的直径和离子行进路径的长度来实现离子通道在受限空间中的调节作用，并首次提出了一种基于Randles-Sevcik方程的跨通道离子转移理论。这种巧妙的设计策略为研究复杂的跨通道系统提供了一种有效的手段。
Ion transport is especially crucial in normal body function, which is regulated by specialized ion channels. In this report, the simple hydrophilic alumina nanochannel is constructed at liquid/liquid (L/L) interface to simulate veritably and compactly complex cross-channel ion transfer processes of living systems in a similar physiological saline environment. The selectivity and regulation that are known for being two important characteristics of ion channels were achieved due to controllable electrosurface properties of alumina nanochannel. This channel shows good selectivity for ion with low electronegativity. The regulatory role of ion channel in confined space was achieved by varying diameters of nanochannel and lengths of ions travel path. In addition, a new theory based on the Randles-Sevcik equation is proposed for evaluation of cross-channel ion transfer in this article for the first time. The ingenious design strategy is demonstrated to be a useful means for investigating the complex cross-channe...
