Patent ID: 10222365

Abstract:
A method for forming a droplet interface bilayer (DIB) comprises the steps of: (1) providing an assembly that includes a housing contained within an enclosure, wherein the housing includes at least one aperture that comprises a cis portion and a trans portion, at least one cis electrode receptacle and at least one trans electrode receptacle, wherein the cis electrode receptacle is operatively connected to the cis portion, and the trans electrode receptacle is operatively connected to the trans portion; (2) inserting an electrode into each of the cis and trans electrode receptacles; (3) introducing an oil/lipid phase to the enclosure such that the oil/lipid phase flows into the housing through the aperture; (4) delivering at least two aqueous droplets to the oil/lipid phase in such a manner that at least one aqueous droplet is disposed within the cis portion of the aperture and at least one aqueous droplet is disposed within the trans portion of the aperture; and (5) lowering a level of the oil/lipid phase in the cis and trans portions of the aperture to cause the aqueous droplets in the cis and trans portions to expand and move closer to one another until the aqueous droplets contact one another thereby forming the lipid bilayer at the location at which the aqueous droplets contact one another.
