New Applications of Magnetic Field to Human Friendly Materials and Human Supportive Systems

Developments of characterization techniques of magnetophoretic mobility were performed to explore clinical and biochemical applications in a study on human-friendly materials. Conceptually, magnetic drug delivery using particulate carriers is very efficient for delivering a drug to a localized disease site. Very high concentrations of chemotherapeutic or radiological agents can be achieved near the target site, for example in a tumor, without any toxic effects to normal surrounding tissue. Here, a feasibility study of magnetic microparticles capable of adsorbing bioactive compounds was made in order to confirm the capability of in vivo usage of the magnetic microparticles. In another application for human supportive systems, magnetic properties were utilized to detect/characterize pain, comfort, and other feelings utilizing the SQUID system. All applications developed here were related to development of human friendly materials and human supportive systems utilizing a magnetic field.
