Electron paramagnetic resonance (EPR) biodosimetry
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001Abstract 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, 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

Lipid oxidation studied by electron paramagnetic resonance (EPR)
2021Electron 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 ...

Chapter 15. Introduction to Electron Paramagnetic Resonance (EPR) of Nitroxides
2021The 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.

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 ...

Study of Metalloproteins Using Continuous Wave Electron Paramagnetic Resonance (EPR)
2014Electron paramagnetic resonance (EPR) is an invaluable tool when studying systems with paramagnetic centers. It is a sensitive spectroscopic method, which can be used with dilute samples in aqueous buffer solutions. Here, we describe the basic procedure for recording an X-band EPR spectrum of a metalloprotein sample at low temperature.

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).

The use of Electron Paramagnetic Resonance (EPR) in the probing of the nanodielectric interface
2007 IEEE International Conference on Solid Dielectrics, 2007EPR (sometimes annotated as ESR) has been carried out on functionalized nanoscale silica embedded in crosslinked polyethylene (XLPE) in comparison with the base resin. In situ EPR measurements under an applied electric field have been carried out, and the technique is outlined.

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 ...
