Abstract
A solid state molecular sensor having an aperture extending through a thickness of a sensing material is configured with a continuous electrically-conducting path extending in the sensing material around the aperture. A supply reservoir is connected to provide a molecular species, having a molecular length, from the supply reservoir to an input port of the aperture. A collection reservoir is connected to collect the molecular species from an output port of the aperture after translocation of the molecular species from the supply reservoir through the sensing aperture. The sensing aperture has a length between the input and output ports, in the sensing material, that is substantially no greater than the molecular length of the molecular species from the supply reservoir. An electrical connection to the sensing material measures a change in an electrical characteristic of the sensing material during the molecular species translocation through the aperture.
