In this paper, a new concept of magnetic nanoparticles as magneto-opticalmarkers is proposed, and a "magneto-optical gate" effect is explored.High-sensitivity detection of magnetic nanoparticles (MNPs) was developed basedon this principle. Under irradiation from monochromatic light with a wavelengthmuch larger than the size of a given MNP, Rayleigh scattering occurs on the MNPsurface. The MNPs anisotropic and orientate themselves into chains, meaningthat the Rayleigh scattering now decreases under magnetic field excitation.After applying an AC magnetic field of frequency f, the transmitted lightpassing through the MNPs reagent generates an AC signal with a frequency of 2f.Moreover, the 2f signal disappears after removal of the magnetic field. Thiscreates a "magneto-optical gate" effect. The instantaneous and highly sensitivedetection of magneto-optical markers with a concentration of 0.2 {\mu}g/mL andan effective optical path length of 10 {\mu}m is realized based on this"magneto-optical gate" effect.
