Electron Spin Resonance Studies

Electron Spin Resonance Studies is a research topic within Biophysics. Science Explorer counts 30k research works in it since 1950. 10.0% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the application of Electron Spin Resonance (ESR) in studying biomolecular systems, including distance measurements using nitroxide compounds, protein dynamics, and the assessment of redox status and oxidative stress. The papers also cover techniques such as pulsed EPR spectroscopy, spin labeling, and the use of EPR in magnetic resonance imaging.
