    In contrast to the type of two-sample measurement used in conventional nephelometric immunoassay, a methodology to achieve a one-sample nephelometric immunoassay is developed in this work. Magnetic nanoparticles instead of latex particles are used as scattering centers. The experimental results show that the sensitivity of assaying avidin or c-reactive protein increased about three times under the action of the magnetic field in nephelometric immunoassay using magnetic nanoparticles.
