Time evolution of an individual nanovesicle exposed to solute concentration ${\mathsf{\Phi }}_{\mathrm{S}}=0.025$ close to the binodal line, which is located at ${\mathsf{\Phi }}_{\mathrm{S}}^{\ast }=0.0275$ for solubility $\zeta =0.625$: At time $t=0\mathsf{\mu }$s, the volume of the vesicle is reduced from $\nu =0.80$ to $\nu =0.75$ and then kept constant at this latter value. The vesicle responds to this volume decrease by closing and reopening its neck in a recurrent fashion. This recurrent process of neck closure and neck opening persists for at least $90\mathsf{\mu }$s, see next Figure 30, which displays the time evolution of the neck diameter [29].
