PCT No. PCT/DE95/01458 Sec. 371 Date Nov. 4, 1997 Sec. 102(e) Date Nov. 4, 1997 PCT Filed Oct. 17, 1995 PCT Pub. No. WO96/12176 PCT Pub. Date Apr. 25, 1996The invention concerns an analyte selective sensor for the qualitative and/or quantitative determination of ions or substances contained in solution. The proposed sensor (1) comprises at least one analyte-specific layer (3) deposited on an inert carrier (7) and in contact with the solution; this analyte-specific layer consists of a liquid, solid or semi-solid material and is in contact with at least two electrodes (5, 6). The layer (3) selectively removes the analyte from the solution so that its own electrical characteristics, such as resistance, conductivity, admittance or impedance, change as the analyte is taken up.
