, independent of the GUV size, while asymmetric division happens at lower osmolarity ratios. Remarkably, we show that a suitable osmolarity change can be triggered by water evaporation, enzymatic decomposition of sucrose or light-triggered uncaging of CMNB-fluorescein. The latter provides full spatiotemporal control, such that a target GUV undergoes division whereas the surrounding GUVs remain unaffected. Finally, we grow phase-separated vesicles from single-phased vesicles by targeted fusion of the opposite lipid type with programmable DNA tags to enable subsequent division cycles.
