Figure 8: Duration of changes in the physicochemical properties of aqueous IgG colloids after exposure to a magnetic field (8 Hz) and mechanical impact (12 Hz). Changes in fluorescence intensity (**a**), refractive index (**b**), optical density (**c**), concentration of dissolved molecular oxygen (**d**). Protein concentration: 1 mg/mL. Time was counted from the beginning of parameter measurement. *—statistically significant differences relative to unexposed samples (_t_-test, \(p\) < 0.05). exposed to a magnetic field, the optical density increased by approximately 5%. When exposed to mechanical shaking, the optical density indicator at all studied exposure times was not statistically different from the control values, although it tended to decrease. In general, the data obtained are consistent with the data presented in Figure 5a. When exposed to a magnetic field, the increased optical density values compared to the control persisted for at least 5 min. A total of 10 min after exposure, the optical density of the colloids did not differ from the control values. The duration of change in the concentration of dissolved molecular oxygen in aqueous IgG colloids after exposure to a magnetic field (8 Hz) and mechanical action (12 Hz) was studied (Figure 8d). It has been shown that when exposed to a magnetic field for 20 min, there is no significant change in the concentration of dissolved molecular oxygen in protein colloids. When exposed to mechanical shaking, the concentration of dissolved molecular oxygen increased by approximately 10%, which is consistent with the data presented in Figure 6b. When exposed to shaking for at least 10 min, the concentration of molecular oxygen dissolved in the aqueous IgG colloid remained increased compared to the control. A total of 20 min after exposure, the fluorescence intensity did not differ from control values. Thus, it has been shown that after the end of exposure to a magnetic field or mechanical stirring, the change in the properties of aqueous IgG colloids persists for at least 5-10 min. Influence of Magnetic Field and Mechanical Action by Pipettingon the Physicochemical Properties of Water  
In these experiments, an aqueous protein colloid and water were mixed in a ratio of 1/100, and in another, control series of experiments, water and water. This is due to the fact that our existing installation can mix solutions exactly in the current ratio. Obviously, with a single pipetting (mixing)of an aqueous protein colloid and water, a protein colloid is also obtained, albeit with a concentration one hundred times less (0.01 mg/mL). Therefore, we sequentially diluted the colloid 12 times in a row. As a result, we obtained a solution with an imaginary protein concentration of 10\({}^{-24}\) mg/mL (\"IgG (mix)\"). Although the protein concentration in this solution is less than Avogadro's number, although a number of researchers believe that particles of the original substance may remain in such solutions [84; 85]. For control, we carried out similar procedures and acted on a water-water mixture 12 times (\"Water (mix)\"). The resulting mixtures were exposed to an external magnetic field with frequencies of 8 and 50 Hz; no mechanical impact was used. The impact of an alternating magnetic field with frequencies of 8 and 50 Hz on the electrical conductivity of H\({}_{2}\)O was investigated (Figure 9a). It has been shown that the specific electrical conductivity of H\({}_{2}\)O does not change under the impact of an alternating magnetic field with frequencies of 8 and 50 Hz. In the \"Water (mix)\" group, the specific electrical conductivity of water does not change significantly after the exposure of an external magnetic field with frequencies of 8 and 50 Hz. In the \"IgG (mix)\" group, the specific electrical conductivity of the sample decreases when exposed to an alternating magnetic field with a frequency of 50 Hz and in the absence of exposure to a magnetic field.
