During the preparation of high dilutions, repeated external vibration (shaking) is used. We hypothesized that it was the vibration treatment, and not the negligible content of the initial substance, that underlies the activity of highly diluted preparations. In order to test this, the vibration was separated from the dilution process. After vibrating two tubes together on a vortex mixer (one containing water and the other the initial substance) the electrical conductivity and radio frequency radiation intensity of water differed from the unvibrated control, and the ability to exert a modifying effect on the target solution appeared, as assessed using ELISA and terahertz spectroscopy, appeared. Thus, the properties of the neutral carrier (water) changed after non-contact exposure to the initial substance. We have named this process ‘crossing’ and its products ‘aqueous iterations of the initial substance’. Several aqueous iterations with different physical properties were obtained, some of which have a modifying effect and others cause various chemical (catalytic) and biological (antiviral) effects similar to those of the initial substance. This indicates that during crossing, substances enter into post-vibration supramolecular interactions. At the nanoscale level, aqueous iterations and the initial substance are structurally symmetrical, which allows us to assume that the preservation of the symmetry of substances subjected to vibration treatment is the basis of the post-vibration interaction phenomenon.

Objectives. It was recently discovered that water samples with modified physicochemical properties can be obtained by successive vibration treatment of intact water together with a solution of a substance located in separate closely spaced vials. We refer to such samples as iterations. By adding the vibrational iterations into the initial substance, the physicochemical properties of the latter are changed, i.e., they demonstrate post-vibration activity. In addition, it has been shown that vibrational iterations can be obtained using water treated with a magnetic field as the initial substance. On this basis, we may hypothesize that the phenomenon of post-vibration activity is universal. To confirm this hypothesis, water treated with an electric signal having various parameters (electrochemically activated water) was used as the initial substance for the preparation of vibrational iterations.Methods. The physicochemical properties of vibrational iterations, which were obtained from electrochemically activated water, were studied by conductometry, terahertz spectroscopy, and radiometry. The effect of the initial substance or its vibrational iterations on intact water (a neutral carrier) was evaluated by dynamic light scattering. For this purpose, the intensity of light scattering by the sample and the hydrodynamic diameter of optical heterogeneities were measured. The attenuation coefficient of an additional electric signal applied to the samples was determined.Results. The obtained vibrational iterations differ from intact water and their mixtures with intact water in terms of specific electrical conductivity, power flux density of microwave radiation, as well as in the contribution of the main (Debye) relaxation process to the overall dielectric response. Mixtures of vibrational iterations with water also differ from intact water in terms of the size of optical heterogeneities. By analogy with the vibrational iterations for which solutions of high- and low-molecular-weight substances were used as the initial substance, vibrational iterations obtained using electrochemically activated water can be classified into different groups (fractions) according to their physicochemical characteristics. Different degrees of changes in the physicochemical characteristics are observed depending on the parameters of the electric signal used to obtain the initial substance. The efficiency of electrical signal propagation in these mixtures, as estimated by the signal strength attenuation coefficient, is additionally changed. The addition of the initial substance (electrochemically activated water) to intact water also leads to changes in the physicochemical properties of the resulting mixture compared to the control. Depending on the parameters of the electric signal used to obtain the initial substance, the magnitude of changes in the physicochemical characteristics of these mixtures similarly varies.Conclusions. The fundamental possibility of obtaining vibrational iterations from electrochemically activated water similarly to vibrational iterations prepared in other studies, was demonstrated. This confirms the universality of the phenomenon of post-vibration.

A new class of biologics is obtained using the technologically processed of antibodies (TPA), which are used as the initial substance, and their dilution at each stage is accompanied by a controlled external vibrational (mechanical) treatment. This article focuses on the development and validation of a novel technique that can be applied for assessing the identity of TPA-based drugs. It has previously been found that after such treatment, the resulting solution either acquired new properties that were not present in the initial substance or a quantitative change in properties compared to the initial substance was observed. The use of mechanical treatment during the manufacture of the TPA-based drugs can cause the formation of new bonds between the solvent and antibody molecules. These changes manifest themselves in altered adsorption at the surface of the test solutions, which results in the formation of a near-surface film. One of the indicators of such events is the change in the surface temperature of the solution, which can be analyzed using high-resolution thermography. Unlike other methods, the high-resolution thermography allows the near-surface layer of a heterogeneous aqueous solution to be clearly visualized and quantified. A number of experiments were performed: seven replicates of sample preparations were tested; the influence of factors “day” or “operator” was investigated during 12 days of testing by two operators. The method also allowed us to distinguish between technologically processed antibodies and samples containing technologically processed buffer. The thermographic analysis has proven to be a simple, specific, and reproducible technique that can be used to analyze the identity of TPA-based drugs, regardless of the dosage form tested.
