To investigate whether the microphase separation of lipids affected the formation of porous structures of capsular DNA coacervates, we first observed the distribution of cationic lipids (DOTAP) at the oil-water interface of the microdroplet. Figure shows a comparison between the positions of DNA and DOTAP, where DNA was stained with 4',6-diamidino-2phenylindole (DAPI; blue) and the cationic lipid was stained with a fluorescent variant of
