RIKEN Center for Biosystems Dynamics Research Next-Generation Magnet Development Collaboration Unit
Unit Leader: Yoshinori Yanagisawa (Ph.D.)
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.
