The power of nuclear magnetic resonance spectroscopy lies in its high resolution, while the technique’s weakness is its low sensitivity. One way to boost NMR signals is through dynamic nuclear polarization (DNP), in which microwave irradiation transfers spin polarization from electrons of a stable radical to the nuclear spins of interest. A research team has now demonstrated signal enhancement of two to three orders of magnitude for room-temperature carbon-13 NMR experiments (Nat. Chem. 2017, DOI: . . .
