Abstract:
Zero- and ultra-low field NMR (ZULF-NMR) is a modality of NMR experiment that do not require strong magnets with applications ranging from molecular spectroscopy and chemical-reaction monitoring to dark-matter searches and exotic physics. However, it suffers from low sensitivity. In this work we combine dissolution Dynamic Nuclear Polarization (dDNP) to enhance biomolecules signals in a ZULF-NMR experiment. We discuss the scope of this hyperpolarization technique for ZULF NMR, such as the sample transfer and paramagnetic relaxation caused by the polarizing agent in DNP. We believe this technique can become an established choice for hyperpolarization in ZULF NMR.
