Abstract

A device for controlled transport of ions is provided comprising an ion source element and an ion target element both conducting ions of a first class e.g. cations, and an ion selective element which conducts ions of a second class e.g. anions. The device further comprises a transport element, which receives ions from the ion source element and releases them to the ion target element in response to an electrochemical potential difference provided across the ion transport element. In use a first electrochemical potential is applied to the control element, which increases the concentration of ions of said second class, which increased concentration in turn increases the ion transport rate of ions of said first class in the ion transport element.
