A new immunosensor integrated to a flow system has been developed. It is based on magnetic immunoparticles immobilized on a solid-state transducer using a magnetic field. The described technique renews the immunoparticles reproducibly for each analysis allowing a good measurement precision. Hie developed experimental approach permits the implementation of an automated immunoassay that is quick (analytical cycle <30 min) and sensitive in the micromolar concentration range. The system was applied to the determination of rabbit immunoglobulin G as an analyte model.
