Dynamic nuclear polarization surface enhanced NMR spectroscopy.
Aaron J. Rossini,Alexandre Zagdoun,Moreno Lelli,Anne Lesage,Christophe Copéret,Lyndon Emsley +5 more
TL;DR: The successful application of DNP SENS to characterize hybrid materials, organometallic surface species, and metal-organic frameworks is described, which enables the detailed and expedient atomic level characterization of the surfaces of complex materials at natural isotopic abundance and opens new avenues for NMR.

TOTAPOL: a biradical polarizing agent for dynamic nuclear polarization experiments in aqueous media.
TL;DR: This paper describes the synthesis and characterization by EPR and DNP/NMR of an improved polarizing agent 1-(TEMPO-4-oxy)-3-(TemPO- 4-amino)propan-2-ol (TOTAPOL), which has the additional important property that it is compatible with experiments in aqueous media, including salt solutions commonly used in the study of proteins and nucleic acids.

TL;DR: In this paper, it was shown that surface NMR spectra can be greatly enhanced using dynamic nuclear polarization, which transferred from the protons of the solvent to the rare nuclei at the surface, yielding at least a 50-fold signal enhancement for surface species covalently incorporated into a silica framework.

Nuclear magnetic resonance of laser-polarized noble gases in molecules, materials, and organisms.
TL;DR: In this article, the authors describe the principles and magnetic resonance applications of laser-polarized noble gases, including void-space imaging of organisms and materials, NMR and MRI of living tissues, probing structure and dynamics of molecules in solution and on surfaces, and NMR sensitivity enhancement via polarization transfer.
