Electron paramagnetic resonance (EPR) spin trapping of biological nitric oxide.
Journal of Chromatography B, 2007Nitric oxide (NO) is a free radical species with multiple physiological functions. Because of low concentrations and short half-life of NO, its direct measurement in living tissues remains a difficult task. Electron paramagnetic resonance (EPR) spin trapping is probably one of the best suitable platforms for development of new methods for ...

Linewidth, field, and frequency in electron paramagnetic resonance (EPR) spectroscopy
JBIC Journal of Biological Inorganic Chemistry, 2022EPR spectroscopy requires a combination of fixed microwave radiation and resonant external magnetic field. Bigger is not necessarily better in that low-frequency and -field EPR (LFEPR) can provide useful information as well as reduced linewidths that can allow better observation of hyperfine coupling. More importantly, LFEPR allows very low g values to

Experimental methods in chemical engineering: Electron paramagnetic resonance spectroscopy‐EPR/ESR
The Canadian Journal of Chemical Engineering, 2020SummaryElectron paramagnetic resonance (EPR) spectroscopy, also known as electron spin resonance spectroscopy (ESR), utilizes absorption of microwave radiation by unpaired electrons in a magnetic field. The interaction between the unpaired electron(s) and nearby magnetic nuclei helps identify paramagnetic species and can provide information about the ...

Room Temperature Electron Paramagnetic Resonance (EPR) Signal Storage
1969 G-MTT International Microwave Symposium, 1969The concept of a spin echo was first introduced and subsequently observed in a system of nuclear spins by E. L. Hahn in 1950. Later experiments performed by R. J. Blume in 1958 first demonstrated the phenomenon in electron spin systems. These echo experiments have since been the subject of a considerable amount of research performed by Mims, et.

Biomedical applications of electron paramagnetic resonance (EPR) spectroscopy
Biomedical Spectroscopy and Imaging, 2012EPR spectroscopy is the most straightforward-to-use technique for studying free radicals and other paramagnetic species and has therefore established itself in biomedical research and for clinical applications. EPR found its applications in oximetry, where this technique allows repeated measurements of oxygen in tissues – also in vivo and in ...

Electron paramagnetic resonance (EPR) spectroscopy: Food, biomedical and pharmaceutical analysis
Biomedical Spectroscopy and Imaging, 2020Electron paramagnetic resonance (EPR) spectroscopy can be applied as an effective and non-invasive spectroscopic method for analyzing samples with unpaired electrons. EPR is suitable for the quantification of radical species, assessment of redox chemical reaction mechanisms in foods, evaluation of the antioxidant capacity of food, as well as for the ...

Probing Alpha-Synuclein Conformations by Electron Paramagnetic Resonance (EPR) Spectroscopy
2019Electron paramagnetic resonance (EPR) spectroscopy in combination with site-directed spin labeling is ideally suited to study structure, dynamics, and interactions of intrinsically disordered proteins as alpha-synuclein.Here we describe all steps required for a corresponding study: the spin labeling procedure, sample preparation, spectroscopic ...

Electron-paramagnetic resonance (EPR) and light-induced EPR investigations of CuGaSe 2
Thin Solid Films, 2000The chalcopyrite compound CuGaSe2 is considered as potential absorber material for thin film solar cells due to its suitable optoelectronic properties. We investigated intentionally undoped bulk material that is used as source material in a thin film deposition process by electronparamagnetic resonance (EPR) and light-induced EPR (LEPR).
