We play the magic of magnetism

Nuclear Magnetic Resonance (NMR) is a powerful analytical and characterization technique that has been widely used in chemistry, materials science, biochemistry and medical diagnosis. The uniqueness of NMR stems from its high chemical resolution, its non-invasive nature, and the capability to offer a full range of structural and molecular information.

Typically, NMR can be categoried into NMR spectroscopy which is used for chemical analysis and magnetic resonance imaging (MRI) which is used for biomedical diagnosis. The NMR spectrscopy is further separated into solution-state NMR which is dedicated to liquid samples and solid-state NMR which is dedicated to solid samples. In addition, the diffusion and relaxation measurement by NMR are widely applied in fields of geophysics (for well-logging) and food industry.

The "Supermagnetic" NMR research group now consists of two joint laboratories: one in Institute of Translational Medicine, Shanghai Jiao Tong University and the other in Department of Chemistry, Zhejiang University. The interest of the group includes the development of NMR techniques (e.g. advanced pulse sequences for solid-state NMR, ultrahigh field imaging, dynamic nuclear polarization) and the frontier explorations in the areas of functional materials and biomedicines.

We spin the world of chemistry

We develop advanced NMR methodologies for the study of the fundamental chemistries in biomedical systems and functional materials. These methodologies include the pulse programs for spectroscopy, strategies of micro-imaging and the instrument of hyperpolarization. We gather the comprehensive information based on NMR characterizations to deepen the knowledge of biomedical functions and to improve the design of future materials.

What we have

 

Solid-state NMR

Ultrahigh-field Imaging

In-situ & Operando NMR

Dynamic Nuclear Polarization

What we do

Strong Magnets

The "Supermagnetic" group runs several high-field NMR systems with magnetic field strength from 9.4 to 18.8 Tesla. (> 100,000 times stronger than the earth's magnetic field. ~ 10 times stronger than typical medical MRI). These top-end NMR instruments enable a full range of NMR experiments, including spectroscopy and imaging.

High Resolution

"Supermagnetic" group pursues better resolutions of NMR in energy, space and time. New modeling strategies quantify weak intermolecular interaction energies. New pulse sequences detect the changes happening during microseconds and miliseconds period. Novel ultrahigh-field MRI probes the morphologies at the micron level.

High Sensitivity

NMR is an insensitive characterization technique due to the weak nuclear spin polarization. It often requires miligrams of sample and hundreds of repeated measurements. "Supermagnetic" group is engaged in the development and applications of hyperpolarization techniques which aim to enhance the NMR signal by orders of magnitude.

NMR Spectroscopy

Superconducting NMR instruments can resolve "tiny" frequency shifts that are less than 1 part per million. Such high frequency resolution enables the distinction of chenmical bonds and weak intermolecular interactions. The "Supermagnetic" group studies the spectroscopy of solid matters and biological samples to understand the underlying chemistries.

NMR Imaging

MRI see through bodies non-invasively and it is sensitive to the soft and flowing compartments. "Supermagnetic" group utilizes the micro-imaging probe together with the strong magnets to study biological tissues and small animals. The micro-imaging under an ultrahigh field can have at least 10X better spatial resolution than clinical MRI scanners.

Multi-Perspective

"Supermagnetic" group tries to assess the sample of interest (e.g. tissues or nanomaterials) through multiple angles. For example, we will detect different nuclear spin signals such as 1H, 13C, 23Na, 31P etc. We will use different pulse sequences such as 2D correlation, exchange or recoupling methods. We will combine different techniques such as X-ray, IR, electron microscopy, simulations altogether.
