Phase transition induced morphological changes in lipid vesicles — •Christian Leirer, Achim Wixforth , and Matthias Schneider — Institut für Physik (Biophysik), Universtät Augsburg, Universitätsstraße 1, D-86159 Augsburg

Phase transition in lipid membranes are accompanied by dramatic changes in the area per molecule and their elastic properties. Using Micropipett aspiration, AFM, fluorescence and light microscopy we studied basic phenomena in membranes, that depend strongly on the phase state and explain them in the theoretical framework of membrane elasticity. A variety of effects showing strong similarities to biological systems are dicussed.
