  • NMR relaxometry can provide information on paramagnetic as well as diamagnetic compounds in solution by analyzing nuclear-spin relaxation times, and, operated at ultra-low magnetic fields, slow processes can be studied. Here, the authors employ zero and ultra-low magnetic fields using an atomic magnetometer as a simple, portable, robust, inexpensive, and sensitive tool to analyze chemical solutions and biofluids.

  • Zero- and ultralow-field (ZULF) nuclear magnetic resonance (NMR) has emerged as a complementary technique to conventional high-field (≳1 T) NMR, however, the ability to distinguish heteronuclear coupling remains challenging due to the low abundance of certain nuclei. Here, the authors apply non-hydrogenative parahydrogen-induced hyperpolarization to identify naturally abundant molecules, and demonstrate the detection of pyridine derivatives at a concentration level of ~1 mM.
