Early Stage Diagnosis of Oral Cancer Using 1H NMR–Based Metabolomics
Neoplasia: An International Journal for Oncology Research, 2009 Oral cancer is the eighth most common cancer worldwide and represents a significant disease burden. If detected at an early stage, survival from oral cancer is better than 90% at 5 years, whereas late stage disease survival is only 30%.

Using metal-organic frameworks to confine liquid samples for nanoscale NV-NMR [PDF]
, 2022 Atomic-scale magnetic field sensors based on nitrogen vacancy (NV) defects in diamonds are an exciting platform for nanoscale nuclear magnetic resonance (NMR) spectroscopy. The detection of NMR signals from a few zeptoliters to single molecules or even single nuclear spins has been demonstrated using NV-centers close to the diamond surface.

High-resolution NMR studies of antibiotics in cellular membranes
Nature Communications, 2018 Antibiotics that target the peptidoglycan precursor lipid II are promising templates for next-generation antibiotics. Here authors use solid-state NMR and monitor lipid II-binding antibiotics, such as nisin, directly in cell membranes.

Non-Uniform Sampling Reconstruction for Symmetrical NMR Spectroscopy by Exploiting Inherent Symmetry [PDF]
arXiv, 2023 Symmetrical NMR spectroscopy constitutes a vital branch of multidimensional NMR spectroscopy, providing a powerful tool for the structural elucidation of biological macromolecules. Non-Uniform Sampling (NUS) serves as an effective strategy for averting the prohibitive acquisition time of multidimensional NMR spectroscopy by only sampling a few points ...

PSYCHE Pure Shift NMR Spectroscopy.
Chemistry, 2018 Broadband homodecoupling techniques in NMR, also known as "pure shift" methods, aim to enhance spectral resolution by suppressing the effects of homonuclear coupling interactions to turn multiplet signals into singlets.

Dynamic Nuclear Polarization Opens New Perspectives for NMR Spectroscopy in Analytical Chemistry.
Analytical Chemistry, 2018 Dynamic nuclear polarization (DNP) can boost sensitivity in nuclear magnetic resonance (NMR) experiments by several orders of magnitude. This Feature illustrates how the coupling of DNP with both liquid- and solid-state NMR spectroscopy has the potential

Achieving the ultimate precision limit in quantum NMR spectroscopy [PDF]
npj Quantum Inf 6, 83 (2020), 2019 The ultimate precision limit in estimating the Larmor frequency of $N$ unentangled rotating spins is well established, and is highly important for magnetometers, gyroscopes and many other sensors. However this limit assumes perfect, single addressing, measurements of the spins.

Materials Characterization by Dynamic Nuclear Polarization-Enhanced Solid-State NMR Spectroscopy.
Journal of Physical Chemistry Letters, 2018 High-resolution solid-state NMR spectroscopy is a powerful tool for the study of organic and inorganic materials because it can directly probe the symmetry and structure at nuclear sites, the connectivity/bonding of atoms and precisely measure ...
