Abstract

A device for sensing ions comprising: a pair of electrodes (10, 12), each electrode having a plurality fingers (20), said fingers arranged in an interdigitated manner in relation to each other; a bottom (30) and a top sensor (32) membrane sandwiching said pair of electrodes (10, 12); and a substrate (40) housing said sensor membranes (30), said substrate having an opening to allow said ions to come into contact with said sensor membranes (30, 32). A pair of contact pads (50, 52) is provided, each contact pad (50, 52) attached and in electrical connection with each electrode (10, 12). The sensor membranes (30, 32) may comprise a plurality of nanowires (60) or nanotubes grown on or around the fingers (20), with an electrical insulating layer (70) between said nanowires and said fingers.
