2023 Elsevier Inc.Dynamic nuclear polarization (DNP) improves the sensitivity of NMR spectroscopy by the transfer of electron polarization to nuclei via irradiation of electron-nuclear transitions with microwaves at the appropriate frequency. For fields > 5 T and using g 2 electrons as polarizing ...
Dynamic nuclear polarization (DNP) is one of the most powerful and versatile hyperpolarization methods to enhance nuclear magnetic resonance (NMR) signals. A major drawback of DNP is the cost and complexity of the required microwave hardware, especially
magic angle spinning DNPMRINMRDynamic nuclear polarization (DNP) is a versatile option to improve the sensitivity of NMR and MRI. This versatility has elicited interest for overcoming potential limitations of these techniques, including the achievement of solid-state polarization enhancement at ambient ...
Nuclear magnetic resonance (NMR) spectroscopy is a powerful and popular technique for probing the molecular structures, dynamics and chemical properties. However the conventional NMR spectroscopy is bottlenecked by its low sensitivity. Dynamic nuclear polarization (DNP) boosts NMR sensitivity by orders of...
In this review, rather than exhaustively covering every hyperpolarization method, we will focus on two extraordinary in-situ hyperpolarization techniques for boosting NMR intensity, namely dynamic nuclear polarization (DNP) and chemically induced dynamic nuclear polarization (CIDNP). DNP leverages the strong...
The technique of dynamic nuclear polarization (DNP) to enhance the intrinsically low sensitivity of an NMR experiment has been around since the early 1950s. While the technique is not new, recent advances in microwave technology, mainly driven by new developments in telecommunication technology, magne...
The article in Angewandte Chemie discusses a new method for characterizing native bacterial biofilms using high-sensitivity dynamic nuclear polarization (DNP) enhanced solid-state NMR. This technique allows for the observation of NMR signals of biofilms composed of bacteria and extracell...
