摘要: A method to detect beta-lactoglobulin (BLG) is described. The method includes the steps of adding a known concentration of hydrogen peroxide to a sample known to, or suspected of containing BLG; and electrolyzing the sample using a working electrode at a fixed potential sufficient to electrolyze BLG, and measuring a current signal within the sample. A diminution of the current signal in the sample as compared to a corresponding current signal from a standard solution containing a known concentration of hydrogen peroxide and no BLG indicates that the sample contains BLG.

摘要: A device is presented having reversibly changeable and optically readable optical properties. The device comprises a substrate having an electrically conductive surface and carrying a redox-active layer structure. The redox-active layer structure may be a monolayer or a multi-layer structure and is configured to have at least one predetermined electronic property including at least one of electrodensity and oxidation state. The electronic property of the layer structure defines an optical property of the structure thereby determining an optical response of the structure to certain incident light. This at least one electronic property is changeable by subjecting the redox-active layer structure to an electric field or to a redox-active material. The device thus enables effecting a change in said electronic property that results in a detectable change in the optical response of the layer structure.

摘要: The silver electrode coated with carbon nanotubes is an indicator electrode for microtitrimetry by differential electrolytic potentiometry. The electrode is made by first positioning at least one silver wire electrode within a reaction zone of a floating catalyst chemical vapor deposition reactor. A ferrocene catalyst is evaporated within the floating catalyst chemical vapor deposition reactor, and an inlet gas is fed therein to carry the evaporated ferrocene catalyst into the reaction zone. The inlet gas includes hydrogen and a carbon source, such as acetylene. The reaction zone is then heated for deposition of carbon onto the at least one silver electrode to form at least one silver electrode coated with carbon nanotubes. The electrode is cooled and then removed from the reactor.
