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 will conduct research on cutting-edge magnet technology that integrates high-temperature superconductor wire, coils, and joints as a functional ultra-high magnetic field magnet for NMR. Based on the technology, we will develop the world’s highest magnetic field 1.3 GHz (30.5 Tesla) class NMR magnet as well as ultra-compact NMR magnets that do not consume liquid helium, to contribute to the research of biosystems dynamics through analyses of biological samples.

Research Theme

  • NMR
  • High-temperature superconductor
