Abstract: | Giant unilamellar vesicles (GUVs) are deposited on glass microfibers. The vesicles adopt the classical "onduloidal" shape of liquid droplets on fibers. They spread by two simultaneous mechanisms: envelopment and emission of a precursor film. This film spreads faster than on a uniform plane surface and eventually stops, signaling the presence of defects on the rod. This fast spreading tenses the vesicles; transient pores open on the GUVs and the internal liquid leaks out. This process leads to a new technique for fiber coating. |
