MAGNETIC PARTICLE FOR THERAPEUTIC TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide an improved process using magnetic particles for inducing cell death which is not dependent on high strength and/or high frequency variation of a magnetic field, and also on the procedure for inducing local or overall temperature rise in a tissue.

SOLUTION: Magnetic particles are used in therapeutic applications to disrupt biological materials. The particles have intrinsic magnetization, and this magnetization is stabilized by inherent magneto-crystal line anisotropy and/or shape anisotropy. By applying a magnetic field, the magnetic particles are induced to rotate when localized at a target biological material, thereby disrupting this material.
