We investigate the shape transformation of a vesicle incorporated with a long and flexible polymer. First a scaling argument is given to demonstrate the initiation of membrane protrusion for small curvature regimes. For large curvature, we develop a statistical mechanics model using grand canonical partition functions of the polymer to study the effects of chain conformations on the membrane. It is found that the polymer loops with the ends adsorbed or anchored on the membrane play a major role on vesicular budding transition. © 2000 American Institute of Physics.
