System and Method Using Coupler-resonators for Electron Paramagnetic Resonance Spectroscopy

A coupler-resonator for electron paramagnetic resonance (EPR) spectroscopy in subjects has a wire loop formed into a coupling loop, a central transmission portion, and sensor loops. The sensor loops hold EPR sensor materials and are coated with biocompatible plastic. The coupler-resonator is implanted in a subject, the subject in a nonuniform magnetic field with a pickup coil for RF response measurement apparatus near the subject's skin and inductively coupled to the coupling loop. Resonances are measured at multiple sensor loops distinguished by sweeping magnetic field or radio frequency. A biopsy sampler has an outer needle with sensor loop and a central sampling needle with cavity for biopsy samples and EPR sensor material. A device for EPR of fingernails has sensor loops in a partial glove for holding loops next to fingertips.; A device for EPR of teeth has sensor loops in plastic chips that can be held between the teeth.
