Sensor for analyte detection in fluid by measuring conductivity of coat - arranged on carrier contacting pair of electrodes interacting with analytes and coating consists of layer of fullerene to provide sensor with long term stability

摘要

Steam or water facilitating an interaction is added to the fluid medium and/or the analytes and/or the fullerene, in such a manner, that the analyte and the fullerene possess a similar proton affinity. The fullerene coating has a metallic doping. The pair of electrodes (3, 4) arranged in double chamber formation have a fullerene coating of C60 and/or C70. The concn. of the fullerene coating (6) is greater than 0.1 microgramme per sq. cm. ADVANTAGE - Sensor has long term stability and indication is completely reversible.
