Biocompatibility: bioengineering aspects.

Bioengineers have contributed to biocompatibility research. Many materials have been designed, synthesized and characterized by use of various analytical instruments. The blood compatibility of materials has been studied by focusing on the blood-material interfacial reactions.

Application of magnetic field for biological response modification.

The study of magnetic effects on biological system was started in response to Dr. Nose's wish for the development of extracorporeal immunomodulation therapy. In the extracorporeal immunomodulation system, monocytes or lymphocytes in blood are stimulated by the interactions with immune-active materials.

A magnetic fluid seal for rotary blood pumps: effects of seal structure on long-term performance in liquid.

A magnetic fluid (MF) seal enables mechanical contact-free rotation of the shaft and hence has excellent durability. The performance of an MF seal, however, has been reported to decrease in liquids. We developed an MF seal that has a "shield" mechanism, and a new MF with a higher magnetization of 47.
