Abstract

The concept that the cellular membrane is a critical structure to be affected by microwaves has been generally prevalent in recent years1–3. Therefore much attention has been given to study on natural and artificial membranes. Artificial bimolecular lipid membranes (BLM) modified with channel-forming substances have proved adequate models to determine the effect of microwaves on the functioning of ionic channels in the membrane. We have succeeded in estimating the microwaves action on the parameters of both a single ionic channel and a membrane with a lot of channels. A substantial effect of microwaves on the conductance of ionic channels formed by antibiotics: alamecithin, amphotericin B, gramicidin A has been found. It has been shown that the effect of microwaves depends on microwave intensity, exposure time, electrolyte concentration and ion type4.
