Free Radical Detection with the EMXnano
30 Aug 2018Some of the most abundant radicals produced in natural biochemical reactions are reactive oxygen species (ROS) such as hydroxyl, hydroperoxyl and superoxide radicals, and reactive nitrogen species (RNS), such as nitrogen monoxide and peroxynitrite. The major reason to measure ROS and RNS in biological systems is to determine whether they play a role in physiological or pathophysiological processes. Detection and characterization of radicals in biological materials is the sole method for direct detection of free radicals done using EPR (electron paramagnetic resonance) methodology.

NMR and EPR SpectroscopyNuclear magnetic resonance (NMR) spectroscopy is used to resolve the local chemical environment of atomic nuclei with spin, revealing information on molecular structure, dynamic processes and chemical reactions of organic molecules, from proteins to synthetics. Electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) spectroscopy is used to detect and quantify paramagnetic species in a sample, including free radicals as transition metal ions. By immersing the sample in a strong magnetic field, both NMR and EPR spectrometers probe the sample with either radio waves or microwaves respectively. A range of benchtop, solid-state and time domain NMR spectrometers & EPR spectrometers are available, as well as NMR tubes, NMR solvents, software, coils, and magnets.

Voltages can be measured using patch clamping, automated workstations, electrophysiology rigs or cell based assays. Specific cell lines, manipulators and microinjectors are also available for electrophysiology research.Electron Magnetic ResonanceAlzheimers ResearchAlzheimer�s disease is a neurodegenerative condition characterized by progressive memory loss and cognitive decline.
