title: Magnetophoretic velocity of microorganic droplets adsorbed by dysprosium(III) laurate in water.
abstract: By using an improved apparatus for the observation of magnetophoresis, the magnetophoretic velocity of 2-fluorotoluene droplets including lauric acid was measured in aqueous dysprosium(III) solution. The magnetophoretic velocity of pure 2-fluorotoluene droplets was proportional to the square of the radius. On the other hand, the velocity of the organic droplets including lauric acid in the dysprosium(III) solution showed a deviation from the square radius relationship, more remarkably in smaller droplets than 2 microm in radius. These results indicated that the dysprosium(III)-laurate complex was formed at the liquid-liquid interface. This study is the first report on the detection of the interfacial complex by the magnetophoresis of the microdroplet.
