Electron paramagnetic resonance (EPR) spin trapping of biological nitric oxide

Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2007
Nitric 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 ...

Lipid oxidation studied by electron paramagnetic resonance (EPR)

open access: yes, 2021
Electron paramagnetic resonance spectroscopy (EPR) allows the detection and quantification of radicals generated during autoxidation of lipids. Even though the high reactivities and very low steady-state concentrations limit the direct detection of lipid-derived radicals to near rigid systems at low temperatures, then the spin trapping technique makes ...

Probing Alpha-Synuclein Conformations by Electron Paramagnetic Resonance (EPR) Spectroscopy

Methods in Molecular Biology, 2019
Electron 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) biodosimetry

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
Abstract Radiation-induced electron paramagnetic resonance (EPR) signals were first reported by Gordy et al. [Proc. Natl. Acad. Sci. USA 41 (1955) 983]. The application of EPR spectroscopy to ionizing radiation dosimetry was later proposed by Brady et al. [Health Phys. 15 (1968) 43].

Linewidth, field, and frequency in electron paramagnetic resonance (EPR) spectroscopy

JBIC Journal of Biological Inorganic Chemistry, 2022
EPR 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

Biomedical applications of electron paramagnetic resonance (EPR) spectroscopy

Biomedical Spectroscopy and Imaging, 2012
EPR 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) and light-induced EPR investigations of CuGaSe 2

Thin Solid Films, 2000
The 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).

Chapter 15. Introduction to Electron Paramagnetic Resonance (EPR) of Nitroxides

2021
The unpaired electron on a nitroxide makes electron paramagnetic resonance (EPR) the method of choice to characterize the radicals and environment. Anisotropic g-values and anisotropic nitrogen nuclear hyperfine couplings cause EPR spectra of nitroxides to sensitively report their environment and their motion in continuous-wave spectra.
