It has unique properties at a particular location in the electromagnetic spectrum where electronics transitions to photonics. For example, many important biological molecules (e.g., proteins, DNA) and biological cells are characterized by low frequency vibrations (e.g., collective vibrations of the backbone of the molecule, rotation, and weak forces between molecules) in the terahertz spectrum (spectral fingerprinting).
