摘要

电渗透是一种由外加电场诱导液体运动的奇妙效应。反离子聚集在带电表面附近,引发液体质量输运和外电场之间的耦合。在纳米流体技术中,表面起着更大的作用,因此电渗透是最重要的。它对生物和合成纳米孔中的输运特性的影响是微妙而复杂的。因此,透彻理解对充分评估起作用的机制具有挑战性,但又至关重要。在这里,我们回顾了电渗透分析的计算技术的最新进展,并讨论了技术应用,特别是纳米孔传感装置。图形抽象

Electroosmosis in nanopores: computational methods and technological applications
ABSTRACT Electroosmosis is a fascinating effect where liquid motion is induced by an applied electric field. Counter ions accumulate in the vicinity of charged surfaces, triggering a coupling between liquid mass transport and external electric field. In nanofluidic technologies, where surfaces play an exacerbated role, electroosmosis is thus of primary importance. Its consequences on transport properties in biological and synthetic nanopores are subtle and intricate. Thorough understanding is therefore challenging yet crucial to fully assess the mechanisms at play. Here, we review recent progress on computational techniques for the analysis of electroosmosis and discuss technological applications, in particular for nanopore sensing devices. Graphical Abstract

期刊介绍: Advances in Physics: X is a fully open-access journal that promotes the centrality of physics and physical measurement to modern science and technology. Advances in Physics: X aims to demonstrate the interconnectivity of physics, meaning the intellectual relationships that exist between one branch of physics and another, as well as the influence of physics across (hence the “X”) traditional boundaries into other disciplines including: Chemistry Materials Science Engineering Biology Medicine
