title: [Electrodynamics of interactions in electrolyte solutions and their biological significance].
abstract: Attention is drawn to the fact that the interaction of charges in aqueous solutions of electrolytes, such as media having physiological characteristics, depends not only on the distance between interacting charges but also on the frequency that determines their dynamics. This fact has significant consequences for some biological processes and their kinetics. The analysis of reasons for charge shielding, including the dynamic effects, shows that, even at distances exceeding the Debye length, electric interactions in systems similar to physiological are effective provided that charges move with frequencies higher than 250 MHz. For each electrolyte solution, the threshold frequency (Maxwell frequency) can be found, which determines the transition from the conducting to the dielectric mode of interactions of charges in physiological solutions.
