    摘要: A biosensor for detecting an antigen using an antigen/antibody coupling includes: a silicon substrate, at least one interdigital electrode pair structure that is located on the silicon substrate, the electrode pair being interspaced at a maximum distance of 1.0 μm; a counter-electrode on the silicon substrate; a reference electrode; a first layer of protein, covering at least the interdigital electrode structure; a selective second protein layer applied to the first layer and containing a capture antibody selected specifically with respect to the antigen of interest and to which the antigen can be coupled. A sensor signal can be read on the interdigital electrode structure, if the antigen is coupled to the capture antibody by way of a sample to be analyzed that comes into contact with the biosensor and a redox reactive molecule is enzymatically released on the sensor surface by an enzyme-marked detection antibody likewise coupled to the antigen.

    摘要: A gas-sensitive field-effect transistor may be formed from a substrate with a gas-sensitive layer and a transistor processed separately and then assembled. The substrate may be patterned to form spacers by which the height of an air gap between the transistor and the sensitive layer may be adjustable to a relatively precise degree. Formation of the spacers can be achieved by patterning the substrate using material-removal techniques. The height of the spacers may be adjusted in the layer thickness of the gas-sensitive layer and for the transistor fabricated using a CMOS process. Suitable techniques for producing recesses between the spacers include, for example, polishing, cutting, sandblasting, lithographic dry etching, or wet-chemical etching. Suitable materials for the substrate may include, for example, glass, ceramic, aluminum oxide, silicon, or a dimensionally stable polymer. Following preparation of the substrate and the transistor, the two elements of the transistor are joined, for example, using flip-chip methods or adhesive-bonding technology.

    摘要: A method and apparatus for detecting methane in a gas mixture that may contain commonly used solvents including alcohols and acetones is provided which measures a change in electrical resistivity, electrical conductivity or relative permeability caused by the presence of methane gas at a chemically active sensing structure. The apparatus includes two spaced-apart electrodes that are covered with a thin methane-sensitive semi-conductive metal oxide layer. The gas to be tested is heated to a temperature exceeding 740.degree. C. before it contacts the metal oxide layer. Alcohols, acetones and other solvents are oxidized to electrical carbon dioxide and water before they reach the metal oxide layer so that only the less reactive and reducing gas methane reaches the metal oxide layer where it is reduced and increases the conductivity of the metal oxide layer as measured between the two spaced-apart electrodes with an appropriate electrical meter instrument.
