Abstract
A nanopore device includes a membrane having a nanopore extending there through forming a channel from a first side of the membrane to a second side of the membrane. The surface of the channel and first side of the membrane are modified with a hydrophobic coating. A first lipid monolayer is deposited on the first side of the membrane, and a second lipid monolayer is deposited on the second side of the membrane, wherein the hydrophobic coating causes spontaneous generation of a lipid bilayer across the nanopore orifice. Sensing entities, such as a protein ion channel, can be inserted and removed from the bilayer by adjusting transmembrane pressure, and adapter molecules can be electrostatically trapped in the ion channel by applying high transmembrane voltages, while resistance or current flow through the sensing entity can be measured electrically.
