[Possible mechanism of oscillations of the bilayer lipid membrane reflectivity induced by electrostriction].

A mechanism of oscillations of the bilayer lipid membrane (BLM) reflectivity obtained in the paper (3) is proposed for two different light polarisations (R parallel, R perpendicular). The measurements of BLM capacity show inphase R parallel and R perpendicular oscillations appearing with lag time some msec after application of the electric voltage to BLM not connected with bilayer thickness. These oscillations are possibly generated with ripple waves spreading from torus to BLM center and changing BLM curvature. The curvature changes can be registered during BLM reflectivity measurements in the case of special apparatus arrangement and interpreted as seeming R parallel and R perpendicular in phase changes.
