Researchers at the University of Tokyo have produced spherical vesicles surrounded by a membrane that, like the membrane of our cells, has an inner and outer layer composed of different phospholipids. In contrast to conventional methods of creating vesicles, this new method leaves little trace of organic solvent layer between the vesicle membranes and is an important contribution as a fundamental technique for development of artificial cell models.
