Illustration of the experimental setup used for making vesicles by microfluidic encapsulation. (A) A lipid bilayer is formed between two aqueous droplets in a chamber independent from the inkjet. (B) Inkjet nozzle is inserted into the chamber holding the bilayer and steered within range of the bilayer to form unilamellar vesicles by moving the chamber. This alignment procedure occurs on a microscope where the formation process can be recorded. Fluid flows continuously from the inkjet orifice to maintain the solution concentration inside the nozzle.
