Abstract
The 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.
Claims51
Analyte-selective sensor for at least one of qualitative and quantitative detection of at least one of ions and materials contained in solutions, wherein said sensor (1, 2) comprises at least one analyte specific layer (3, 8) of at least one of a liquid, solid and semi-solid material, in contact with the solution, applied to an inert carrier (7) and being solely ionically conductive, and which is in connection with at least two electrodes (5, 6), the layer (3, 8) containing coupling members which selectively remove the analyte from the solution, so that, by absorption of the analyte, at least one of the ionic resistance, the ionic conductivity, the ionic admittance and the ionic impedance of the layer (3, 8) is altered.
