“…One of them is the ability to control ongoing reactions even if these reactions are invisible to the human eye or other equipment. This has been repeatedly confirmed in our research [9][10][11][12][13][14].…”

Early identification of viruses leads to more efficient disease management and control, and is extremely important. A possible new approach for creating virus sensors is the Electromagnetic echo effect (EMEE). An important feature is that the signal from EMEE is highly dependent on the state of the irradiated body. This makes it possible to control ongoing reactions, even if these reactions are invisible to the human eye or other equipment. This article shows the possibility of registering reaction occurring in the presence of an avian coronavirus causing infectious bronchitis, strain Massachusetts. The same methodology can be applied for other types of viruses as well.

“…Any changes in the properties of a fluid, or processes taking place in it, are transferred to the solid-fluid interface and can be thus detected [16,17]. It has been previously demonstrated that the EMEE can be utilized to distinguish between different liquids [18]; to determine the octane factor of gasoline [19], or the quality of drinking water from the public water distribution system [4]; to control fog parameters, including the presence of impurities in fog [20]; and even to monitor processes in biological fluid samples [21].…”

In our ongoing investigations, we have studied a specific interaction between electromagnetic fields and matter, the so-called Electromagnetic echo effect (EMEE). It enables rapid and contactless investigations of gases, liquids and solids to be performed, since the signal generated as a result of the effect is quite sensitive to all kinds of changes occurring within the studied samples. The effect can be considered universal for all matter and provides analysis in real time. We use this phenomenon to demonstrate the practical possibility to control reactions, occurring between Chicken anemia virus (CAV) and the corresponding antibodies. This methodology can be used for simple but reliable control of similar, otherwise hard to detect, antigen-antibody reactions, in order to confirm the presence of a certain viral species. The approach offers a high level of safety, since it enables measurements to be taken remotely, thus limiting exposure to contagion. We further discuss the possibility to register the presence of SARS-nCoV-2 in an attempt to address current global pandemic.

“…An important step for control of the presence and the concentration of chemical compounds (considered impurities) in artificially generated fog is to develop a sensor system. The current sensor [11] used in this work is developed based on results grouped under the working name "surface photo-charge effect" (SPCE). This effect is quantified when there is an interaction between matter (gas, liquid, or solid) and an electromagnetic field.…”

Lab experiments related to artificial fog studies are limited due to instrument sensitivity to small fog and aerosol particles; therefore, the goal of this work is to evaluate aerosol solute effects on fog physical properties in a lab environment. To reach the goal, an automated fog-generating system was designed and that includes controlled chemical compounds dissolved in pure water. In the analysis, the impact of changing the mass concentration of potassium dihydrogen phosphate—KH2PO4, urea-CO(NH2)2, and potassium hexacyanoferrate trihydrate-K3(Fe(CN)6) on fog droplet size spectra is studied, because visibility is directly related to fog droplet spectra and aerosol composition. In the experiment, various microphysical conditions, including fog droplet size and volume concentration, were analyzed as a function of changing aerosol composition/spectra and fixed thermodynamic conditions. The results showed that fog droplet size spectra vary with the addition of chemical impurities to the pure water volume. For example, increasing KH2PO4 concentration compared to distilled water volume resulted in a higher mean particle size, which led to faster droplet settlement, and that resulted in cleaning air more efficiently compared to pure water fog. Overall, both issues and challenges of the experimental fog generating system with respect to water and aerosol solutions resembling CRBN (chemical, radiological, biological, and nuclear agents) characteristics are provided and evaluated.
