N2 - Dynamic behaviors of nano-scale magnets in biomaterials are observed under external magnetic fields. Although magnetic nano-particles have been proposed for use as biomedical purposes, the interactions between the coat of the magnet and the solvent molecules are not so clear. Therefore basic knowledge on information of the dynamic movement in various materials should be accumulated. Using strong photon beams in SPring-8 facility, we trace movement of magnetic fluid and investigate the response of the nano-scale magnets under external magnetic fields in various materials. In this paper, we show results of the observation in agarose gel, eggs, leaf of plant, and oil. Finally it is shown that one can calculate the velocity of a magnetic cluster of 0.5mm size from a theoretical point of views, and obtain a good agreement with the experimental data in oil. On the basis of all these results, it is concluded that the movement of magnetic fluids can be precisely controlled by external magnetic fields in various materials.
