Non-equilibrium Dynamics of Giant Vesicles — •Hans-Günther Döbereiner — Departments of Biology and Physics, Columbia University, New York, NY 10027

I will review our work on the dynamics of giant lipid vesicles and polymersomes out of chemical and/or mechanical equilibrium. Phospholipid vesicles under prolonged attack of the enzyme phospolipase C exhibit lateral phase separation coupled to a pronounced morphological transition of the membrane [1]. Further, I will discuss the morphological relaxations observed in temperature [2,3] and pH [4] jump experiments, respectively.
