Electron Paramagnetic Resonance in Biology

Biophysical Journal, 1962
A review of the theories of electron paramagnetic resonance in biology is presented, including a discussion of the nature of the physical observation, followed by examples of materials of biological interest. Iq discussing these examples, information is presented in terms of the nature of the starting material under observation rather than the nature ...

Electron paramagnetic resonance of manganese-doped strontium titanate [PDF]

Cerâmica
Electron paramagnetic resonance (EPR) spectra of manganese-doped strontium titanate were investigated for several Mn concentrations. The spectra of Mn2+ and Mn4+ ions were observed and attributed, respectively, to Mn ions occupying Sr2+ and Ti4+ sites ...

Nanographene oxide-methylene blue as phototherapies platform for breast tumor ablation and metastasis prevention in a syngeneic orthotopic murine model

Journal of Nanobiotechnology, 2018
Background In the photodynamic therapy (PDT), the photosensitizer absorbs light and transfers the energy of the excited state to the oxygen in the cell environment producing reactive oxygen species (ROS), that in its turn, may cause cell damage.

Electron paramagnetic resonance of VN–VGa complex in BGaN

APL Materials, 2023
A metastable photoinduced electron paramagnetic resonance (EPR) signal at low temperatures is reported for GaN alloyed with boron (i.e., BxGa1−xN) epitaxial layers grown at temperatures ranging from 840 to 1090° C. An isotropic EPR line with g = 2.004 is

The theory of the reentrant effect in susceptibility of cylindrical mesoscopic samples [PDF]

, 2006
A theory has been developed to explain the anomalous behavior of the magnetic susceptibility of a normal metal-superconductor ($NS$) structure in weak magnetic fields at millikelvin temperatures. The effect was discovered experimentally by A.C.

Electron paramagnetic resonance microscopy using spins in diamond under ambient conditions

Nature Communications, 2017
Magnetic resonance spectroscopy is one of the most important tools in chemical and bio-medical research. However, sensitivity limitations typically restrict imaging resolution to ~ 10 µm. Here we bring quantum control to the detection of chemical systems
