<p>A system and corresponding method for carrying out an amperometric immunoassay of a target antigen in which a solid phase support is provided, having an oxidised cellulose paper on which is immobilised an antibody that specifically binds to target antigen and at least one enzyme. An electrode is juxtaposed with the paper, which is in communication with a reaction chamber having suitable receiving means for providing thereto a test fluid having said target antigen and the chemicals required for the particular immunoassay reaction and a redox reaction occurring in response thereto to be carried out. Suitable electronic measuring means are operatively connected to the electrode for monitoring a response of said at least one electrode to said redox reaction that occurs in the reaction chamber. In particular, the reaction chamber, receiving means, paper and electrode are in the form of a disposable cartridge which is mountable to a separate non-disposable electronic measuring means when the assay is to be performed.</p> |
