FIELD: medical engineering; immunology. SUBSTANCE: device has working chamber 1 and comparison chamber 2. Each chamber includes microporous solid-body silicon membrane 3 with immobilized immune complexes on working chamber membrane and with one of components of immunochemical pair on comparison chamber membrane positioned between two electrodes, golden electrode-acceptor (anode) 4 and cathode (source-of electrodes) 5. Golden electrode 4 is immersed in solution of 4.4-dipyridyl 6, and cathodes 5, into solution of cytochrome C (red) 7. Voltage source 8 is connected to electrodes for processing the data coming from electrodes. Current is supplied to analog-to-digital converter 10 through differential amplifier 9, and then signals from both chambers are processed by computer 11. EFFECT: higher results of analysis. 2 dwg
