“…Terahertz (THz) wave is an electromagnetic wave with a frequency range of 0.1–10 THz (1 THz = 10 12 Hz) and a wavelength of 0.03–3 mm ( Figure 1 ). Due to the immaturity of THz wave generation, transmission, and detection systems, this band was once referred to as the "THz Gap" in the electromagnetic spectrum ( Globus, 2016 ; Smye et al., 2001 ). With the promising advancement of scientific methodologies in materials and optics since the 1980s, this gap has been filled, resulting in the rapid development and progress of THz technology.…”

Summary Terahertz (THz) waves are ranged between microwave and infrared region in the electromagnetic spectrum. THz technology has been demonstrated promising potential for biomedical applications. Exploration of biological effects of THz waves has emerged as a critical new area in life sciences. It is critical to uncover the effects of THz waves on complex biological systems in order to lay out the framework for THz technology development and future applications. Specifically, THz radiation has been shown to affect the nervous system, including the structure of nerve cell membranes, genes expressions, and cytokines level. In this review, we primarily discuss the biological impacts and mechanisms of THz waves on the nervous system at the organisms, cellular, and molecular levels. The future application perspectives of THz technologies in neuroscience are also highlighted and proposed.

“…The vibrational spectral fingerprint of biomolecules lies in this frequency range [12,13] (and many materials of interest have unique spectral fingerprints in the terahertz range [14,15]), therefore, it can be used for theirs identification, making THz spectroscopy a promising sensing tool for biomedical applications and disease diagnosis.…”

Terahertz Spectroscopy - A Cutting Edge Technology

In this chapter, we present a number of sensitive measurement modalities for the study and analysis of human cancer-affected colon and gastric tissue using terahertz (THz) spectroscopy. Considerable advancements have been reached in characterization of bio-tissue with some accuracy, although too dawn, and still long and exhaustive work have to be done towards well-established and reliable applications. The advent of the THz-time-domain spectroscopy (THz-TDS) test modality at a sub-picosecond time resolution has arguably fostered an intensive work in this field's research line. The chapter addresses some basic theoretical aspects of this measurement modality with the presentation of general experimental laboratory setup diagrams for THz generation and detection, sample preparation aspects, samples optical parameters calculation procedures and data analysis.
