Effect of terahertz electromagnetic waves on neurons systems

Biological effects of in vitro THz radiation exposure in human foetal fibroblasts

“…Similar cellular ultrastructural alterations, such as abnormal membranes and morphology of mitochondria, disruption and disorganization of microfilaments and microtubules were observed after THz and radiofrequency exposure on neural structures of different animal models [32,33].…”

Invited Review Article: Current State of Research on Biological Effects of Terahertz Radiation

“…Study 13. In 2008, Olshevskaya et al examined the direct effects that THz radiation have on isolated neurons from Lymnaea stagnalis [20]. Exposures were conducted with a THz FEL using the following exposure parameters: frequencies of 0.7, 2.49, and 3.69 THz; H=0.3-30 mWcm 2 , exposures ≥1 min ( Table 2).…”

“…In recent years, many timely investigations have been performed to investigate the possible biological effects associated with THz radiation [12][13][14][15][16][17][18][19][20][21][22]. Unfortunately, however, a comprehensive review has not yet appeared in the literature which both discusses the fundamental interaction mechanisms, and also critically reviews the bioeffects studies that have been conducted to date.…”

An overview of cancer treatment by terahertz radiation

“…It was also believed that low level THz radiation mighit interfere with the interaction of protein recognition molecules, such as enzymes and antibodies, with small molecular substrates [17]. It was reported that neurons in vitro exposed to powerful THz radiation (over 30mW/cm 2 , 1min ), at a specific frequency, developed infringements on the morphology of the cellular membranes and intracellular structures, yet at lower powers (1-10mW/cm 2 ) the morphological changes were poorly expressed [18 ]. Furthermore, THz irradiation (130GHz over 2min) can alter the membrane permeability [19 ], so it is promising that THz be used to promote disintegration or drug effects of cancer cells.…”
