The Effects of THz Irradiation on Cellular Actin Filament

摘要

The influence of the terahertz (THz) radiation for deep tissues has been neglected due to its strong absorption by water molecules on the surface of the skin. In this report, we found for the first time the demolishing effect of the THz pulsed radiation on actin filaments located in aqueous solution with a few millimeters in depth. This result demonstrates that the THz photon energy propagates in water with several millimeters in depth, possibly as shockwave, and affected actin filaments. Thus, it is implicated that THz waves have the potential to manipulate functions of proteins and cells in deep tissues.
