Nonenzymatic electrochemical method for determination of the measles virus antigen using the synthesized IgG-(Fe3O4-SiO2) conjugate as the signal label

An electrochemical method for determining viral antigens was developed in relation to the measles virus antigen. Using inverse adsorption voltammetry and the synthesized conjugates of antibodies with the Fe3O4-SiO2 nanocomposite particles as the signal label, a sensitive, easily measurable analytical signal was obtained.
