Nanoparticle-antibody conjugates as a potential label in the electrochemical immunoassay.

Modern medical diagnosis characterized by the use of a wide variety of viral agents detection methods. Identify the pathogen, especially in severe diseases, it is important for prediction of further disease progression, and to choose the right method of treatment. The rapid identification of the virus at the alleged contamination, allowing urgently undertake countermeasures, it is a particularly actual problem. The present work is devoted to development approach to the determination of antigens of viruses, which consist in producing an electrochemical signal from the immunocomplex "target analyte (antigen) – conjugate antibodies and nanoparticles Fe3O4», localized on the surface of the electrode.
