摘要：
In the paper the results about changes of the current-voltage characteristics (I-V) of the surface-barrier structures (SBS) after the deposition of myoglobin (Mb) and its specific monoclonal antibodies (AT) are presented. It was shown that the SBS structures with ultra-thin metal film (Ni-Si) or with ultra-thin layer of the porous silicon (PorSi-Si) are sensitive to the presence of the protein or its specific immune complex on their surfaces. The response of the system depended on the conditions of the specific complex formation. The characteristic optimum of the thickness of Ni film or the layer of the porous silicon was revealed when the changes of the I-V characteristics had a maximum level.
