Abstract: A single molecule filter includes: a membrane including: a first surface; a second surface; and a membrane aperture disposed in the membrane and traversing the membrane from the first surface to the second surface, the membrane aperture provided to communicate a single molecule across the membrane; and a nanotube disposed on the membrane and including: a first end disposed on the first surface of the membrane; a second end disposed distal to the first surface; and a tubular aperture extending along the nanotube from the first end to the second end, the tubular aperture provided to communicate the single molecule from the second end of the nanotube to the membrane aperture.
