Abstract:
1. A method of forming droplets comprising the steps of: forming a sheath flow from three inlet streams wherein a first stream comprising a first solution is sandwiched between second and third streams comprising a second solution; dissolving a first type of amphiphilic molecules in the second solution; generating a droplet from the first stream by controlling shear forces generated by the second and third streams acting upon the first stream, wherein the step of generating a droplet includes encapsulating the droplet with the amphiphilic molecules to form a monolayer vesicle; passing the monolayer vesicle through the first and second solution interface to form a bilayer vesicle, wherein the first and second solution interface is formed by a third solution flowing through two downstream input channels.
