LOCATIONAL CONTROL METHOD OF THE MAGNETIC MATERIAL IN BODY

摘要

A method for controlling the location of a magnetic body in a living body is provided to allow accurate location of a magnetic fluid used for treating or diagnosing cancers to a cancer cell site, and to improve drug delivery in the human body and cancer treating efficiency while minimizing side effects. A method for controlling the location of a magnetic body in a living body comprises: forming a rotational magnetic field by using an external tri-axial alternating current magnetic field applying system and applying the rotational magnetic field to magnetic nanoparticles(50) or magnetic nano-rods to cause the magnetic nanoparticles or nano-rods to be rotated by magnetic torque; causing the magnetic nanoparticles or nano-rods to proceed under the rotational force; and controlling the proceeding direction by varying the rotation surface of the rotational magnetic field through a location controller(40).
