NMR Relaxometry Accessing the Relaxation Spectrum in Molecular Glass Formers

International Journal of Molecular Sciences, 2022
It is a longstanding question whether universality or specificity characterize the molecular dynamics underlying the glass transition of liquids. In particular, there is an ongoing debate to what degree the shape of dynamical susceptibilities is common ...

Spotting Frozen Curd in PDO Buffalo Mozzarella Cheese Through Insights on Its Supramolecular Structure Acquired by 1H TD-NMR Relaxation Experiments

Applied Sciences, 2021
The addition of frozen curd (FC) during the production process of “Mozzarella di Bufala Campana”, an Italian cheese with Protected Designation of Origin (PDO), is a common fraud not involving modifications of the chemical composition in the final product.

High Resolution 31P Field Cycling NMR Reveals Unsuspected Features of Enzyme-Substrate-Cofactor Dynamics

Frontiers in Molecular Biosciences, 2022
The dynamic interactions of enzymes and substrates underpins catalysis, yet few techniques can interrogate the dynamics of protein-bound ligands. Here we describe the use of field cycling NMR relaxometry to measure the dynamics of enzyme-bound substrates

Single-Cell Hyperthermia: Diamond Quantum Thermometry Reveals Thermal Control of Macrophage Polarization. [PDF]

Adv Mater
Photothermal nanodiamonds with quantum sensing capabilities generate lysosome‐confined hyperthermia, enabling simultaneous temperature and radical detection via diamond sensing. This localized thermal and oxidative stress drives pro‐inflammatory (M1) macrophage polarization, revealing a new strategy for precision immunomodulation through subcellular ...

Diamond-Based Nanoscale Quantum Relaxometry for Sensing Free Radical Production in Cells.

Small, 2022
Diamond magnetometry makes use of fluorescent defects in diamonds to convert magnetic resonance signals into fluorescence. Because optical photons can be detected much more sensitively, this technique currently holds several sensitivity world records for

A Magnetic Resonance-Relaxometry-Based Technique to Identify Blood Products in Brain Parenchyma: An Experimental Study on a Rabbit Model

Frontiers in Veterinary Science, 2022
Magnetic resonance relaxometry is a quantitative technique that estimates T1/T2 tissue relaxation times. This has been proven to increase MRI diagnostic accuracy of brain disorders in human medicine. However, literature in the veterinary field is scarce.
