Abstract: An artificial lipid bilayer membrane formation device is disclosed. It includes: an upper solution chamber whose bottom has a small hole; a lower solution chamber having a support layer; and lipid solution exclusion device. Lipid solution is applied to the small hole, and the lipid solution exclusion device excludes surplus lipid solution without changing a hydraulic pressure so that the lipid solution is in contact with the support layer, thereby forming an artificial lipid bilayer membrane on the small hole.

Abstract: An artificial lipid bilayer membrane formation device is disclosed, which includes: an upper solution chamber (first solution chamber) and a lower solution chamber (second solution chamber), both of which are filled with aqueous solution. It further includes a partition wall disposed between the upper solution chamber and the lower solution chamber so as to part the upper and lower solution chambers from each other. The partition wall has an opening, and a first lipid solution is applied to a portion around the opening, thereby forming an artificial lipid bilayer membrane on the opening. Further, in the formation device, a tubule for lipid substitution is attached to the partition wall so as to be positioned on a bulk phase of the artificial lipid bilayer membrane. A second lipid solution is added via the tubule, thereby forming an artificial lipid bilayer membrane whose lipid composition is changed.

Abstract: The current measuring device includes an upper solution chamber (3) and a lower solution chamber (8) whose bottom has a support layer (5) and measures a current flowing via an artificial lipid bilayer membrane (2) formed on a small hole (4) of the upper solution chamber (3), wherein the lower solution chamber (8) is provided below the upper solution chamber (3) by being surrounded with a bottom plate (6) and an interval keeping member (7a). An internal pressure of the lower solution chamber (8) is dropped so that the artificial lipid bilayer membrane (2) formed on the small hole (4) swells to the side of the lower solution chamber (8) so as to be thinner, and the thinner artificial lipid bilayer membrane (2) is supported by the support layer.
