The Influence of Non-Thermal Coherent Millimeter Electromagnetic Waves on the Thermal Expansion Coefficients of DNA Solutions
Recently it has been shown that the DNA thermal capacity is increased by 1°C after irradiation with 64.5 GHz and 50.3 GHz frequencies resonant for water structure (Kalantaryan et al., 2014). It was supposed that under the influence of non-thermal coherent millimeter electromagnetic waves (MEW) dehydration of [Na+] ions and DNA solution has taken place.
In this study we investigated the effect of MEW (t<90 min of irradiation) on DNA densities depending on temperature. Our measurements show that the density of DNA solution is increased by 10g/cm 3 depending on irradiating time (sensitivity of densitometer was 10g/cm3). Moreover, the experiments indicate no significant change in the coefficient of surface tension of DNA irradiated with MEW suggested non-thermal low intensity radiation transfer into the deeper layers of solution.
According to the densitometric data obtained for buffer and DNA water solution, α thermal expansion coefficient depends on temperature (T) is calculated (Kalantaryan et al., 2014) .
Our calculations of thermal expansion coefficient depends on temperature (T) show that α is increased depends on temperature. However, we found no significant change in MEW radiation for α in 10°C-50°C temperature range. In high temperatures (T>50°C) the thermal expansion coefficient for irradiation buffer and DNA solutions was lower than this for non-radiated. The results on physicochemical parameters of DNA solutions revealed that irradiation with water resonant frequencies leads to no significant change in water structure.
