The use of terahertz radiation in various fields
such as biology and medicine is increasing every year. Meanwhile, people are
increasingly concerned about the mechanism on the interaction between terahertz
radiation and biological system. In this study, we evaluated the effect of the
cellular response of bEnd.3 which exposing to the terahertz radiation in the
range of 0.1-3.5 THz. We collected the spectral data of cells during the
irradiation with a temperature of 20.6°C and a relative humidity of 5%. Meanwhile,
the apoptosis of cell was assessed by Annexin V-FITC/PI kit. As a result, the
apoptosis of cells were inhibited from 0 and 6 hours after terahertz
irradiation and promoted at 12 hours after irradiation. Moreover, we also
calculated the complex dielectric constant of bEnd.3 cells at different
exposures. The results demonstrate that the dielectric loss of cells showed a
slight decrease with the increase of exposure in the range of 0.2-1.4 THz.
