Abstract
An apparatus for single-sided bilayer formation includes a first fluid chamber including a sidewall and a second fluid chamber extending through the sidewall. A barrier wall separates the first and second fluid chambers and includes a nanopore therein across which a planar lipid bilayer (PLB) is formed. In use, an electrolyte is added to the first and second fluid chambers and a lipid/organic solvent mixture is added to the first fluid chamber to form a lipid/organic solvent layer. The electrolyte level within the first fluid chamber is adjusted such that the lipid layer is raised above the barrier wall and a PLB is formed. Electrolyte levels may be adjusted manually or utilizing a fluid level regulator with or without feedback control. Optionally, the apparatus may be in the form of a nanopore array. The apparatus may be incorporated into an ion channel sensing system wherein an electrical current through each PLB is separately recorded.
