Abstract—

The main stages in the development of electrokinetic studies at the Laboratory of Bioelectrochemistry of the Institute of Physical Chemistry, Russian Academy of Sciences, headed by corr. member of RAS Yu.A. Chizmadzhev, are described. Methods of recording and analyzing the results of measuring the electrophoretic mobility of liposomes using dynamic light scattering techniques are briefly overviewed. The advantage of using electrokinetic data in combination with the measurement of the boundary potentials of planar bilayer lipid membranes using the intramembrane field compensation method has been shown. The data obtained in the framework of this approach is illustrated by studies of effects of some membrane-active ions and compounds on the surface and dipole components of the electric field at the lipid membrane interfaces with an aqueous environment.

期刊介绍： Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
