In the context of nanomaterials, EPR works similarly to its application in bulk materials but requires special attention to the size and surface effects. The process typically involves placing the nanomaterial in a magnetic field and irradiating it with microwaves. The unpaired electrons in the nanomaterial absorb the microwave energy at a specific resonance condition. This absorption is then measured to provide information about the electronic environment, magnetic properties, and the presence of defects or impurities within the nanomaterial.
