Modulated pattern formation of phospholipid monolayers on curved surfaces.
Langmuir-Blodgett transfer of a dipalmitoylphosphatidylcholine monolayer onto macroscopically curved mica surfaces results in microscopic patterns of the transferred monolayer that differ from those of films transferred onto a flat mica substrate. On curved surfaces a modulated horizontal striped pattern evolves that has a zigzag boundary at the liquid condensed front of the stripe and a continuous straight boundary at the liquid condensed rear. We propose that the sensitivity of the pattern to the macroscopic curvature of the sample is due to a flow-controlled hydrodynamic instability caused by the subphase flow close to the three-phase contact line.
