EPR in Material Science and Physics

There are many topics of interest within the areas of physics and material science. EPR serves as a valuable tool for delving into various facets such as polymer synthesis and degradation, analyzing paint properties, assessing the purity and stability of photovoltaics, semiconductors, and batteries, and scrutinizing carbon nanotubes. Furthermore, EPR helps the user gather information on the coordination environment of transition metals, rare-earth, and actinide ions.

EPR in Life Science

EPR is a significant tool in the field of life sciences, providinginsight into the structure, function and reaction mechanisms of enzymes, membrane proteins, RNA/DNA. It can also be used to characterize/screenDNP agents. Moreover, using spin-labeled biomacromolecules, users can studytheir structure and dynamics. EPR detects and quantifies reactive oxygen and nitrogen species (ROS/RNS), including nitric oxide.
