Electrifying membranes and lipid demixing

Dr. Rumiana Dimova, Max Planck Institute of Colloids and Interfaces, Science Park Golm, Potsdam

This talk is not going to be about what happens if you plug in a lipid vesicle into the socket, but would elaborate on a number of phenomena induced by electric fields on membranes. In particular, we will focus on electrodeformation, electroporation and electrofusion of membranes and how these processes can be directly visualized under the microscope using giant unilamellar vesicles. These giants are only a few tens of microns large but can nicely show not only deformation and poration of the 5-nm thick lipid bilayer but also phase separation in the membrane. The latter process will be discussed in more detail also in view of protein adsorption and adhesion inducing lipid demixing.
