Terahertz waves and perspectives of terahertz biomedical technologies development

The diagram of comparative development of frequency bands and powers by modern radioelectronic means and apparatus for biomedical technologies has been made up. Terminology and physical basis of selection of the terahertz band of electromagnetic waves are given. Comparative energy characteristics of terahertz and extremely-high frequencies waves are presented, tables of molecular spectrums of atmospheric gases, metabolites, air pollutants, some macro- and microbiological structures, frequency bands of relic background and some substances in the terahertz band are given. It is paid attention to some effects of terahertz waves interaction with biological and physical mediums. The perspective trends of investigations for creation of novel terahertz biomedical technologies are founded. The results of Daphnia magna Strauspsila functional state investigation depending on influence of atmospheric air, exposed to terahertz electromagnetic irradiation, on Daphnia water environment are presented. Also, the investigation results of Daphnia heartbeats frequency change during simultaneous effect of phenol, alternating magnetic field and electromagnetic radiation are given.
