Lipid bilayers are the structure-giving matrix and primary permeation barrier of biomembranes. Specific cellular functions fulfilled by membrane proteins may be regulated by properties of the lipid matrix as well. Technically, they are, for example, used as liposomes for targeted drug delivery. The class introduces the basics of lipid bilayers, including their structure and dynamics, phase transitions, transport of molecules within and across membranes. After six introductory, interactive lectures and a break, each participant shall present a scientific paper and its background to the class. This will be a joint class with the University of Freiburg, Germany, via online.
