Analysis and control of molecule and ion transport in nanopores

在纳米流体系统的合成、测量和分析技术方面的最新进展使人们能够系统地研究尺寸小于10 nm的狭窄受限通道中的离子传输。在如此小的维度中，可以观察到反常的离子输运。对亚10 nm流体通道中离子输运的研究为探索在生理细胞中模拟蛋白质离子通道或在高能量密度燃料电池中模拟质子交换膜的人工离子通道提供了机会。本研究通过外加电场对介孔二氧化硅中的离子输运进行了测量和分析，以便将其有效地应用于各种技术。

Recent advances in synthesis, measurement, and analysis techniques of nanofluidic systems have allowed ion transport to be systematically explored in narrow, confined channels with dimensions of less than 10 nm. In such small dimensions, anomalous ion transport can be observed. The studies of ion transport in sub-10 nm fluidic channels provide opportunities to explore artificial ion channels that can mimic protein ion channels in physiological cells or proton exchange membranes in high energy density fuel cells. In this study, the measurement and analysis of ion transport in well-dimensioned mesoporous silica by applying electric fields were conducted in order to effectively apply them to various technologies.
