Abstract

A mimic of biological blebbing motions constructed by a purely chemical system has been studied to understand nanometer scale structure and their roles in the spontaneous motion. Transition of surfactant lamellar phase was away rom the interface, accompanied with blebbing type deformation of the oil-water interface. This transition was not observed when the deformation was suppressed by a turbid aggregate. Taking this transition and elastic nature of aggregate in account, the blebbing motion of the oil-water interface can be explained successfully. The present result supports that the purely chemical oil-water-surfactant system can be analogous to an active gel showing the cellular blebbing motion.
