Abstract

A device for transport of ions and/or charged molecules between a source and a target electrolyte, comprising: a first electrode provided at or in said source electrolyte, and a second electrode provided at or in said target electrolyte; and wherein said first and second electrodes provides an electrical control of an ion flow, and further comprising means for limiting an electronic current between said source and said target electrodes, such that at least after a voltage is applied a potential difference between said source and target electrodes is maintained, which effects ion transport from said source to said target electrode; wherein the device further comprises an ion- and/or permselective polyelectrolyte for transport ions and/or charged molecules via electrophoresis and functions as an ion-selective membrane; and wherein said polyelectrolyte comprises a cross-linked hyperbranched polymer.
