Project summaryAccording to an existing hypothesis, extracellular water serves as one of the essential targets through which the non-thermal effect of Millimeter Wave (MMW) is realized. However, the nature of MMW-induced non-thermal changes of the physicochemical properties of extra-cellular water, able to modulate the cell metabolic activity, needs scientific clarification. Since water molecules ionization is the most variable water property, it is suggested that the latter could be changed by MMW-induced vibration of water dipoles. Even partial alignment of the water molecules with the electric field will cause pre-existing hydrogen bonding to become bent or broken.
Due to the fact that water ionization changes bring to adequate changes of water specific electrical conductivity (SEC) and specific absorption rate (SAR), these parameters could serve as a marker for detection of non-thermal effect of MW on water ionization.
It is suggested that the proposed comparative study of the effect on physicochemical properties of water and water solutions of MMW, Terahertz (THz), and Infrared (IR) radiations (non-modulated and modulated by low frequency EMF) could allow us to understand the mechanism responsible for non-thermal effects on water and water solutions. The use of the extremely wide frequency region (from MMW up to IR) will promote the establishment of the frequencies (or frequency rage) of electromagnetic radiation and modulation rate which are favorable for non-thermal effects. Because in various frequency regions different mechanisms may be responsible for water behavior, we hope to clarify the origin of the non-thermal effect as well.
Therefore, the overall aim of the present project is to conduct a comparative study of modulated and non-modulated MW, MMW, THz and IR radiation on physicochemical properties of water and water solutions, such as SEC, SAR, specific heat capacity, gas solubility, formation of reactive oxygen species (ROS), and complex dielectric constant. The well-known difficulties of the operation in THz waveband will be overcome by using a recently developed THz time-domain spectrometer (TDS).
