A Slowly Relaxing Rigid Biradical for Efficient Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy: Expeditious Characterization of Functional Group Manipulation in Hybrid Materials
Alexandre Zagdoun,Gilles Casano,Olivier Ouari,Giuseppe Lapadula,Aaron J. Rossini,Moreno Lelli,Mathieu Baffert,David Gajan,Laurent Veyre,Werner Maas,Melanie Rosay,Ralph T. Weber,Chloé Thieuleux,Christophe Copéret,Anne Lesage,Paul Tordo,Lyndon Emsley +16 more
TL;DR: This new nitroxide-based biradical is shown to outperform the polarizing agents used so far in DNP surface-enhanced NMR spectroscopy of materials, yielding a 113-fold increase in overall sensitivity for silicon-29 CPMAS spectra as compared to conventional NMR experiments at room temperature.
Journal ArticleDOI
Intermolecular structure determination of amyloid fibrils with magic-angle spinning and dynamic nuclear polarization NMR.
Marvin J. Bayro,Galia T. Debelouchina,Matthew T. Eddy,Neil R. Birkett,Catherine E. MacPhee,Melanie Rosay,Werner Maas,Christopher M. Dobson,Robert G. Griffin +8 more
TL;DR: Acquisition of low temperature spectra addresses a problem that is frequently encountered in MAS spectra of proteins, and establishes that the PI3-SH3 protein strands are aligned in a parallel, in-register arrangement within the amyloid fibril.
Journal ArticleDOI
Dynamic Nuclear Polarization Enhanced Solid-State NMR Spectroscopy of Functionalized Metal–Organic Frameworks†
Aaron J. Rossini,Alexandre Zagdoun,Moreno Lelli,Jérôme Canivet,Sonia Aguado,Olivier Ouari,Paul Tordo,Melanie Rosay,Werner Maas,Christophe Copéret,David Farrusseng,Lyndon Emsley,Anne Lesage +12 more
TL;DR: Dynamic nuclear polarization (DNP) is applied to enhance the signal of solid-state NMR spectra of metal-organic framework (MOF) materials and enables the acquisition of high-quality 1D 13C solid- state N MR spectra with natural isotopic abundance in experiment times on the order of minutes.
Journal ArticleDOI
Solid-State NMR Spectroscopy on Cellular Preparations Enhanced by Dynamic Nuclear Polarization
Marie Renault,Shane Pawsey,Martine P. Bos,Eline J. Koers,Deepak Nand,Ria Tommassen-van Boxtel,Melanie Rosay,Jan Tommassen,Werner Maas,Marc Baldus +9 more
TL;DR: It is demonstrated that high-resolution ssNMR spectra can be obtained on uniformly C,N-labeled preparations of Escherichia coli whole cells (WC) and cell envelopes (CE), and dynamic nuclear polarization (DNP) has developed into a routine tool to increase the sensitivity of multidimensional ssN MR.
Journal ArticleDOI
Non-aqueous solvents for DNP surface enhanced NMR spectroscopy.
Alexandre Zagdoun,Aaron J. Rossini,David Gajan,Adrien Bourdolle,Olivier Ouari,Melanie Rosay,Werner Maas,Paul Tordo,Moreno Lelli,Lyndon Emsley,Anne Lesage,Christophe Copéret +11 more
TL;DR: A series of non-aqueous solvents combined with the exogenous biradical bTbK are developed for DNP NMR that yield enhancements comparable to the best available water based systems, demonstrating the first DNP surface enhanced NMR characterization of an organometallic complex supported on a hydrophobic surface.
