Abstract

The invention relates to the use of nanoporous membranes (1, 14) and in particular polymer track etched membranes to develop novel electrode surfaces for use in sensor devices. The first type of novel electrode comprises a nanoporous, thin layer of conductive material (2) formed integrally on the surface of a nanoporous membrane. The membrane can be used in combination with one or more nanoporous electrodes to make a conductivity sensor for example. Alternatively, the membrane may then be partially or fully removed before the resultant electrode is put to use to produce an electrode surface comprising a generally planar conducting electrode element the surface of which is covered with one or more projecting nanowires (84). Methods of fabrication are also described.
