Selective Lipid-patterning for Heterologous Giant Liposome Array

This paper describes a methodology that realizes an array of heterologous giant liposomes with gentle hydration. The system consists of an array of micropores on a thin polymer film, which is overlaid on a pair of comb ITO-electrodes. An electrospray deposition (ESD) method allows selective lipid patterning of green and red fluorescent-labeled lipids at the micropores that expose either of the target ITOs. With hydration of the lipid film, we successfully obtained an alternatelycolored giant liposome array on top of the pattern.
