Undulation force, originating from the thermally excited membrane fluctuations, plays a key role in regulating an astounding array of the biological functions of cells,such as cell adhesion, membrane fusion, binding-unbinding transition and membrane selfassembly. Therefore, the study on the undulation force and its laws forms a significant foundation for life science research. In view of the important role of undulation force in the regulation of cellular processes, it has been highly concerned since the co...
