The electron paramagnetic resonance technique is the only spectroscopic technique that allows the direct detection and study of unpaired electrons. Unpaired electrons are widely distributed, such as isolated single atoms, conductors, magnetic molecules, transition metal ions, rare earth ions, ion clusters, doping materials, defective materials, biological free radicals, metal proteins, etc. Many substances do not contain unpaired electrons themselves but produce unpaired electrons upon excitation by light. Therefore, the EPR technique is widely used in physics, chemistry, biology, materials, industry, and other fields.
EPR in Environmental Science
Environmental monitoring, such as air pollution, sewage treatment, transition metals heavy metals, EPRFs.
Site-directed spin labeling (SDSL) in combination with EPR spectroscopy is a rapidly expanding powerful biophysical technique to study the structural and dynamic properties of membrane proteins in a native environment.
EPR in Chemistry
Chemical Analysis such as Structure research of coordination compounds, catalytic reactions, detection of free radicals and antioxidants, detection of reactive oxygen species, kinetics of chemical reactions, polymerization reaction mechanism, catalytic mechanism, chemical dosimeter, etc.
EPR in Material Science and Physics
Single crystal defects, magnetic material properties, semiconductor conductive electronics, solar cells, materials, polymer properties, fiber defects, magnetic molecules, EPR imaging, etc.
EPR in Pharma
The formation of free radicals has long been associated with the toxic side effects of drugs. The temporal behavior of free radicals involved in drug systems can identify, quantify, and monitor by analyzing EPR signals.
EPR in Industry
Physical ageing of organic coatings, the radical protection factor for cosmetics, crystallographic defects in diamond, cigarette filter efficiency, free radical control in petrochemical industry, transition metal oxide in lithium ion battery, etc.
EPR in Biomedical Sciences
Antioxidant characterization, NOx detection, reactive oxygen species ROS, occupational disease protection research, nuclear radiation emergency medical rescue diagnosis classification, cancer chemotherapy, radiation-related studies.
EPR in Food Science
Radiation dose of agricultural products, the shelf life of beer flavor, edible oil rancidity test, alanine dosimeter (EPR dosimetry), antioxidants for food and beverages.
