  • Patent number: 10267784
    Abstract: A nanodevice includes a reservoir filled with conductive fluid and a membrane separating the reservoir. A nanopore is formed through the membrane having electrode layers separated by insulating layers. A certain electrode layer has a first type of organic coating and a pair of electrode layers has a second type. The first type of organic coating forms a motion control transient bond to a molecule in the nanopore for motion control, and the second type forms first and second transient bonds to different bonding sites of a base of the molecule. When a voltage is applied to the pair of electrode layers a tunneling current is generated by the base in the nanopore, and the tunneling current travels via the first and second transient bonds formed to be measured as a current signature for distinguishing the base. The motion control transient bond is stronger than first and second transient bonds.

  • Patent number: 9846141
    Abstract: A mechanism is provided for presenting single strands of a double strand molecule to a membrane. The double strand molecule is driven to a first side of the membrane by an electric field. The membrane has a first and second nanopore spaced apart by a nanopore separation distance. The first strand of the double strand molecule is captured in the first nanopore when driven to the first side of the membrane. The second strand is captured in the second nanopore by having the nanopore separation distance between the first nanopore and the second nanopore corresponding to a strand separation distance between the first and second strands, and/or by having captured the first strand to limit diffusion of the second strand. The first and second strands respectively in the first and second nanopores are individually stretched, by the first and second strands recombining on the second side of the membrane.

  • Patent number: 9222930
    Abstract: A mechanism is provided for forming a nanodevice. A reservoir is filled with a conductive fluid, and a membrane is formed to separate the reservoir in the nanodevice. The membrane includes an electrode layer having a tunneling junction formed therein. The membrane is formed to have a nanopore formed through one or more other layers of the membrane such that the nanopore is aligned with the tunneling junction of the electrode layer. The tunneling junction of the electrode layer is narrowed to a narrowed size by electroplating or electroless deposition. When a voltage is applied to the electrode layer, a tunneling current is generated by a base in the tunneling junction to be measured as a current signature for distinguishing the base. When an organic coating is formed on an inside surface of the tunneling junction, transient bonds are formed between the electrode layer and the base.
