Osmotic deflation of vesicles enclosing two liquid phases
can lead
to bulging of one of the phases from the vesicle body. This budding
process is preceded by a complete to partial wetting transition of
one of the liquid phases on the membrane and depends on the membrane
tensions and the tension of the interface between the enclosed liquid
phases. These tensions dominate in different morphology regimes, the
crossover of which initiates the budding process. In addition, the
degree of budding can be controlled by aspiration via micropipets.
We also demonstrate that the budding direction can be reversed if
there are two external phases in contact with the vesicle.
