Nuclear magnetic resonance (NMR) has become an indispensible tool for chemists, biologists, and medical professionals. NMR is based on splitting of the spin energy states induced by a static magnetic field, and resonant absorption of electromagnetic energy, at levels equivalent to the energy difference between such split spin states. The resonance associated with energy absorption from the electromagnetic field occurs in the microwave region. Thus, NMR, unless aided by extensive modifications like stripe sensor tomography, is unsuitable for bio-imaging on the micron scale because the microwave fields required to produce resonant absorption have wavelengths on the order of millimeters. Other magnetic-resonance-based spectroscopy techniques, including electron spin resonance (ESR), also rely on excitation in the microwave region. While ESR can be successfully employed to study macroscopic parameters like membrane fluidity, the resolution of microwave radiation limits the usefulness of ESR in of bio-imaging.
