Applications
Free radicals
Free radicals are atoms that contain an unpaired electron and highly reactive and unstable molecules that are produced in the body naturally as a byproduct of metabolism (oxidation), or by exposure to toxins in the environment such as tobacco smoke and ultraviolet light. Free radicals have a lifespan of only a fraction of a second, but during that time can damage DNA, sometimes resulting in mutations that can lead to cancer. Antioxidants in the foods we eat can neutralize the unstable molecules, reducing the risk of damage. Electron paramagnetic resonance (EPR) is the only technique that can detect radicals directly.

Materials
As a new type of nanomagnetic material, metal fullerenes nanocomposites with paramagnetic characteristics have important value in magnetic resonance imaging, single-molecule magnet research, spin quantum information research, etc. The electron spin distribution in metal fullerenes can be obtained through EPR technology, to further study the hyperfine interaction between the spin and metal magnetic nucleus and detecting the change of fullerenes spin and magnetism in different environments.
