A mechanism based on Larmor precession theory is proposed, with the interaction target located in charged lipid groups emerging from the membrane surface. The results indicate that specific exposure conditions may enhance membrane permeability.

Abstract

The problem of the interaction between electromagnetic fields and a biological system can be properly faced at cell membrane level. Specifically, in this work, the target of the interaction has been located in the charged lipid group emerging from the membrane surface. A possible mechanism based on the Larmor precession theory is here proposed. The results evidence the possibility of specific exposure conditions that enhance the membrane permeability.
