Abstract
Infrared-terahertz (IRT) resonant absorption complies with unique biomolecule fingerprints, including neurotransmitters, proteins, ribonucleic acid, and deoxyribonucleic acid, rendering it a suitable technology to achieve conformational variations and functional adjustments. Recent research has preliminarily confirmed that IRT waves can reversibly and nonthermally regulate gene expression, transmit biological information, transform protein function, and intervene in the interchange of material at the molecular level. Regarding macroscopic effects, IRT waves can enhance cell motility, improve brain ability, and affect mood. This review article attempts to provide comprehensive insight to illustrate the application of IRT waves in biophysics. Some typical experiments and equipment are summarized to demonstrate how to conduct IRT biophysics research. This cutting-edge field involves interesting research topics spanning physics and biology and opens an avenue to the performance of interdisciplinary research.
