Developing functional high-field magnet for analyzing biological samples

A Nuclear Magnetic Resonance (NMR) spectrometer can analyze the structure of various substances such as biological samples, polymers, nanomaterials, and natural products using a magnetic field. The analytical performance of an NMR improves as the strength of the magnetic field increases. We conduct research and development on cutting-edge magnet technology that integrates high-temperature superconductor wire, coils, and joints as next-generation high-field magnets for NMR. Based on the technology, we will develop the world’s highest magnetic field NMR magnet as well as ultra-compact NMR magnets without consumption of liquid helium, to contribute to the research of biosystems dynamics through analyses of biological samples.

Research Theme

  • NMR
  • High-temperature superconductor
  • Ultra-high magnetic field
