| Abstract: | Real-time observation of a morphologies of a multi-component tubular giant vesicle (tGV), which is a self-assembly composed of plural amphiphiles with different packing parameters, was carried out under application of a magnetic field. A tGV, one of the terminals of which was fixed to a bottom of a cell, exhibited the bending deformation under a magnetic field along the perpendicular direction of the long axis. Moreover, the hysteretic behavior in this deformation was observed associated with the increase and decrease of the magnetic fields repeatedly, regardless of the presence or absence of a paramagnetic species. To understand the hysteretic behavior, the molecular cooperative effect, which stabilizes the bending deformation by replacing of the plural kinds of amphiphiles with different packing parameters within a membrane, must be taken into consideration. |
