Elastic vesicle membrane, cell deformation
|The usual vesicle membranes are formed by bilayers of lipid molecules. These lipid membranes exist everywhere in life and compartmentalize living matter into cells and subcellular structures and present themselves as highly structured interfaces which are essential for many biological functions||The equilibrium shapes of bilayer vesicle membranes have been successfully modeled via the minimization of certain shape energy such as the elastic bending energy. Recently, we have developed effective phase field bending elasticity models and simulation tools for such problems.|
