“…The results of 25 experiments described within this work are still in good correlation with previous works of authors [19,20], and other research groups [21,22], which point to the selective response of biological systems to the application of external ELF MF. Simply, if the combination of ELF-MF parameters does not fulfill certain specific conditions, the biological reaction would be weak, or would not occur at all.…”

The article deals with the possible influence of an extremely low-frequency magnetic field on cellular structures. The work is carried out to verify the change of growth dynamics of exposed samples by application of a time-varying magnetic field, with a specified action value of magnetic flux density, valid in the European Union. The frequency of applied field was preliminarily confirmed as biologically active, under conditions for Ion Parametric Resonance theory, in experimental work focused on targeting Ca2+ ions bound in specific positions on cellular membranes of eukaryotic cells. In thirty experiments, the authors use the dynamics of growth over a time horizon of eight hours to elucidate the effect of the field on the proliferation activity of the cells. Since living beings are exposed to similar electromagnetic fields daily, the presented article shed some light on whether, or not the irradiation has brought a statistically significant effect under conditions specified in ICNIRP guidelines and recommendations.

“…They have provided basic information on the possible biological effects of EMF exposure to living systems. There are few studies focused on the acute or chronic EMF exposure in IF range and its consequence on human health at cellular level in vitro [45][46][47]. Therefore, the investigation of potential adverse or cumulative EMF effect is quite challenging and precise epidemiological studies are needed to confirm the possible negative effects of EMF exposure to humans [15].…”

The progress in technology and science leads to the invention and use of many electrical devices in the daily lives of humans. In addition to that, people have been easily exposed to increased newly generated artificial electromagnetic waves. Exponential use of modern electronic devices has automatically led to increase in electromagnetic wave exposure. Therefore, we constructed the prototype of wireless power charging system to study the biocompatibility of electromagnetic field (EMF) generated by this system on various human cell lines. There are many studies indicating the negative bio-effect of EMF on various types of cells, such as induction of apoptosis. From the other point of view, these effects could rather be beneficial in the way, that they could eliminate the progress of various diseases or disorders. For that reason, we compared the impact of EMF (87 kHz, 0.3–1.2 mT, 30 min) on human normal as well as cancer cell lines based on morphological and cellular level. Our results suggested that EMF generated by wireless power charging systems does not have any detrimental effect on cell morphology, viability and cytoskeletal structures of human neural cells.

“…The E-field induced in the cell culture medium by the MF generated by the developed coil is in the order of 10 −4 V•m −1 . The reported threshold for an E-field to elicit a biological effect is estimated to be around 10 −4 V•m −1 for neutrophil cells [8] and used in research into umbilical cord blood lymphocytes [40]. Thus, it is questionable if the EF generated by the new exposure system can be neglected, and the results obtained for biocompatibility studies can be referred to be caused by the MF.…”

“…where q is the electric charge of the target ion, m is the molecular mass of the target ion, and B DC is the value of static magnetic flux density-the geomagnetic field in this case. The target is calcium ion 40 Ca 2+ with a cyclotron frequency of 29.89 Hz. According to the IPR, the maximal biological effect should be reached at the B AC /B DC ratio of 1.8.…”

Low-Frequency Magnetic Field Exposure System for Cells Electromagnetic Biocompatibility Studies

The advancement in science and technology has resulted in the invention and widespread usage of many electrical devices in the daily lives of humans. The exponential use of modern electronic facilities has increased electromagnetic field exposure in the current population. Therefore, the presented article deals with designing, constructing, and testing a new applicator system developed for cells electromagnetic biocompatibility studies. The applicator system is intended for studying the non-thermal impacts of low-frequency magnetic field on cell cultures growth. Main attention is focused on increasing the capacity of the applicator and effectivity of the experiments. The key idea is to reach high level of the magnetic field homogeneity in an area of interest and the temperature stability during the biocompatibility studies. The applicator system is designed based on numerical simulations and its construction, measurements, and properties evaluation are also reported for proving the applicator’s functionality. The new applicator allows performing five parallel experiments at the same time under the same conditions. The simulation together with the experimental results confirm that the magnetic field homogeneity reaches 99% in the area of interest and the maximum temperature instability is lower than 2% during the experiments. The effectiveness of new applicator is tested and proved during preliminary experiments with Saccharomyces Cerevisiae cells. The observed effects of MF exposure represent maximal stimulation of 74% and maximal inhibition of 49%. The reason why MF with the same parameters induces inhibition in one sample and stimulation in the other will be the subject of further research.
