Gradient in the lattice pattern of underlying bumps imparts directionality to the partitioning and dynamics of the Lo phase in Lo-Ld multibilayer. a) SEM images showing the variation in lattice spacing from top to bottom and presence of surrounding walls in the underlying patterned area. b) Vesicle (circle) has formed at the 400 nm end of the underlying lattice where there is strong partitioning of the Lo phase evidenced by the dark appearance. c) The border of the Lo phase migrates toward the 400 nm end. The vesicle grows from the Lo phase at the 400 nm end as shown at d) 201 min and e) 271 min, reaching a diameter of approximately 40 μm. Scale bars 10 μm unless indicated otherwise.
