Dynamic nuclear polarization (DNP) greatly improves the NMR sensitivity, but its implementation in aqueous solutions is challenging. Here the authors demonstrate carbon polarization enhancement via in situ Overhauser DNP in small biomolecules in wate

Dynamic nuclear polarization (DNP) is a powerful method to enhance NMR sensitivity. Much progress has been achieved recently to optimize DNP performance at high magnetic fields in solid-state samples, mostly by utilizing the solid or the cross effect

In DNP experiments, NMR signal intensity is increased by transferring the much larger electron spin polarization to nuclear spins via microwave irradiation. Here we describe the design and performance of a probehead that makes it possible to perform
