27 April 2010 Micro-electron spin resonance (ESR/EPR) spectroscopy
Author Affiliations +
Electron Spin Resonance, also referred to as electron paramagnetic resonance (ESR / EPR), is the only direct method for measuring free radicals, reactive molecules with unpaired electrons that cause the oxidative breakdown of oils, food products, and also play a role in the biochemistry of disease. We discuss a recently developed miniature, high sensitivity ESR spectrometer called Micro-ESRTM. The technology promises to revolutionize the accessibility of ESR spectroscopy for industrial and scientific users.
