磁性粒子を含むS/O/W エマルション油滴の磁界による挙動制御

Oil droplets of S/O/W emulsion were manipulated by magnetic field. This S/O/W emulsion is safflower oil, containing magnetic particles, dispersed in water. This S/O/W emulsion is prepared using SPG membrane. First, magnetic field were applied to the statically placed S/O/W emulsion by an electromagnet from the side. As a result, the oil droplets moved in the direction of the magnet. Then, the magnetic field were applied to the oil droplets of the S/O/W emulsion flowing in a bifurcated channel branching in two directions. As a result, more than half of the oil droplets were guided to one of the branches. These experiments showed the larger the diameter of the oil droplets and the stronger the magnetic field, the faster the oil droplets moved. The larger the diameter of the oil droplet, the more it was guided to one of the branches.
