Abstract
It has been highly required to analyze the environmental or biological micro–particles noninvasively and nondestructively, since these particles have each characteristic function in the surface and inside the individual particle. Magnetophoresis is a relatively new migration method of particles, which allows us not only to separate particles having different magnetic susceptibility but also to determine the paramagnetic ions in individual particles. In micron–sized particles, the molecule at the surface changes the magnetic susceptibility of particles, because the specific area increases with inversely proportional to the radius of the particle. In this review, we describe the magnetophoretic detection of interfacial adsorption of paramagnetic Dy (III) ion at the 2–fluorotoluene droplet in aqueous solution.
