  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 the
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 sensing devices.
