Theories on structural perturbations of lipid bilayers.
Curr. Opin. Coll. Int. Sci, in press
Structural perturbations of fluid lipid bilayers can be caused by various processes, like insertion of transmembrane inclusions, protein and peptide adsorption, formation of membrane pores, or even by the transition to the inverse hexagonal phase. Theoretical concepts for their energetic description are often based on elasticity theory. There are new insights from both applying this theory to inclusion-containing membranes and from relating elasticity theory to microscopic models of perturbed lipid bilayers.
