In this paper, we developed a microfluidic device for formation of artificial cell membranes (lipid bilayer membranes) and for electrical recordings of transmembrane currents. We succeeded in observing electrical current together with formation of transmembrane α-hemolysin nanopores at the bilayer membrane. In addition, we applied glass for the device material to target long-term stability of the formed bilayer membranes. With further development, we believe that the device will contribute to lower the cost and enhance the data throughput of the functional analyses of membrane proteins related to the drug discovery.
