On The Mechanism Of Low Intensity Laser Irradiation Effects On Virus

Liu TCY et al have suggested the membrane receptor mediated signal transduction mechanism (STM) on photobiomodulation, which was verified by successful applications. In this paper, STM is extended to virus, and called VSTM. The key of VSTM is the conformational changes of envelope glycoproteins, which is realized by light induced electron excitation. As the frequency of the absorption light of envelope glycoproteins is greater than the one of light from UVA (320-400 nm) to IR, the envelope glycoprotein absorption of the light is non-resonant, and its transition rate is extraordinarily small, but can be amplified by the coherent state of the identical and independent envelope glycoproteins. We apply VSTM to discuss the possibility that light from UVA to IR is used to inactivate the coronavirus of severe acute respiratory syndrome.
