Publication date: 2009
Publication number: CN201184874

Abstract: The utility model discloses a molecularly imprinted membrane electrode for fungal toxin detection. The molecularly imprinted membrane electrode comprises an electrode substrate and electrode matrixes, one of the electrode matrixes is connected with a working electrode as a whole through an electrode connecting wire by a terminal block, the other electrode matrix is connected with a counter electrode as a whole through the electrode connecting wire by the terminal block; a layer of polycarbonate is coated on the surface of each electrode connecting wire, and a reaction layer is coated on the working electrode. The molecularly imprinted membrane electrode further comprises a reference electrode which is fixed on the electrode substrate. A layer of carbon nanotubes for nano-synergy is further coated on the working electrode. The molecularly imprinted membrane electrode can realize the fast on-line detection of fungal toxin, the detection limit can be controlled at about 10min, the detection limit is 0.1ng/g; the carbon nanotubes are added in the reaction layer, thereby significantly improving the reaction sensitivity and the detection precision of the prepared electrode; the reference electrode is fixedly arranged on the electrode substrate, thereby allowing the detection to be more accurate.
