[Cooperative analysis of measurements of capacity and optical parameters of bilayer lipid membranes].
On the model of rough bilayer lipid membrane (BLM) a cooperative analysis was carried out of measurements of its capacity and of reflective ability and transmission in the optical range of the wave lengths. A correct estimation of roughness of BLM containing squalene was given, roughness parameters initiated under BLM electrostriction were estimated. Electrostriction mechanism of rough BLM was considered. It has been shown that discrepancies while measuring the elasticity modulus E perpendicular to bilayer plane by capacitive and optical methods are due to some peculiarities of the latter, which in fact measures another elasticity modulus E (at two-sided widening of the bilayer in its plane). The optical and capacitive methods give additional information concerning BLM deformations at electrostriction.
