Module Trap for Magnetic Nanoparticles Concentration

A module magnetic system for magnetic nanoparticle concentration is presented. The system is based on several blocks of magnets with alternative orientations to produce a strong gradient magnetic field. The magnetic system is placed over the free surface of colloid running fluid with magnetic nanoparticles without contact with liquid. Magnetic particles are localized in fluid due to surface tension. The mathematical model of magnetic particles manipulation by the magnetic system and experiment setup were worked up. Mathematical simulation has proved that the magnetic system can provide a strong concentration of practically all magnetic nanoparticles in a small area. A mathematical simulation was confirmed by experimental measurement.
