  • Patent number: 8945404
    Abstract: A mechanism is provided for fabricating nanochannels for a nanodevice. Insulating film is deposited on a substrate. A nanowire is patterned on the film. Insulating material is deposited on the nanowire and film. A first circular hole is formed in the insulating material as an inlet, over a first tip of the nanowire to expose the first tip. A second circular hole is formed as an outlet, over a second tip of the nanowire opposite the first tip to expose the second tip. A nanochannel connects the first and second holes by etching away the nanowire via an etchant in the first and the second holes. A first reservoir is attached over the first hole in connection with the nanochannel at a previous location of the first tip. A second reservoir is attached over the second hole in connection with the nanochannel at a previous location of the second tip.

  • Patent number: 8940148
    Abstract: The present invention provides a nano-fluidic field effective device. The device includes a channel having a first side and a second side, a first set of electrodes adjacent to the first side, a second set of electrodes adjacent to the second side, a control unit for applying electric potentials to the electrodes and a fluid within the channel containing a charge molecule. The first set of electrodes is disposed such that application of electric potentials produces a spatially varying electric field that confines a charged molecule within a predetermined area of said channel. The second set of electrodes is disposed such that application of electric potentials relative to the electric potentials applied to the first set of electrodes creates an electric field that confines the charged molecule to an area away from the second side of the channel.

  • Publication number: 20150021187
    Abstract: A device for passing a biopolymer molecule includes a nanochannel formed between a surface relief structure, a patterned layer forming sidewalls of the nanochannel and a sealing layer formed over the patterned layer to encapsulate the nanochannel. The surface relief structure includes a three-dimensionally rounded surface that reduces a channel dimension of the nanochannel at a portion of nanochannel and gradually increases the dimension along the nanochannel toward an opening position, which is configured to receive a biopolymer.

  • Publication number: 20150001099
    Abstract: A nanodevice includes a nanochannel disposed through a dielectric material. A first electrode is disposed on a first side of the nanochannel, is formed within the dielectric material and has a surface exposed within the nanochannel. A second electrode is disposed on a second side of the nanochannel, is formed within the dielectric material and has a surface exposed within the nanochannel opposite the first electrode. A power circuit is connected between the first and second electrodes to create a potential difference between the first and second electrodes such that portions of a molecule can be identified by a change in electrical properties across the first and second electrodes as the molecule passes.

  • Publication number: 20140312002
    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.

  • Publication number: 20140279791
    Abstract: Disclosed is a novel system, and method to evaluate a prediction of a possibly unknown outcome out of a plurality of predictions of that outcome. The method begins with accessing a particular prediction of an outcome out of a plurality of predictions of that outcome in which the outcome may be unknown. Next, a subsample of the plurality of predictions of the outcome is accessed. The subsample can possibly include the particular prediction. A consensus prediction of the outcome based on the subsample of the plurality of predictions is determined. A proximity of the particular prediction to the consensus prediction is determined. Each prediction is ranked out of the plurality of predictions in an order of a closest in proximity to the consensus prediction to a farthest in proximity to the consensus prediction.

  • Patent number: 8764968
    Abstract: A technique for nanodevice is provided. A reservoir is filled with an ionic fluid. A membrane separates the reservoir, and the membrane includes electrode layers separated by insulating layers in which the electrode layers have an organic coating. A nanopore is formed through the membrane, and the organic coating on the electrode layers forms transient bonds to a base of a molecule in the nanopore. When a first voltage is applied to the electrode layers a tunneling current is generated by the base in the nanopore, and the tunneling current travels through the transient bonds formed to the base to be measured as a current signature for distinguishing the base.

  • Publication number: 20140152291
    Abstract: A mechanism is provided for base recognition of an integrated transistor and nanochannel. A target molecule is forced down to a carbon nanotube a single base at a time in the nanochannel by applying a gate voltage to a top electrode, and/or a narrow thickness of the nanochannel. The nanochannel exposes an exposed portion of the carbon nanotube at a bottom wall, and the top electrode is positioned over the exposed portion. The exposed portion of the carbon nanotube is smaller than the distance between bases to only accommodate the single base at a time. The target molecule is stretched by the narrow thickness and by applying a traverse voltage across a length direction of the nanochannel. The target molecule is frictionally restricted by the narrow thickness of the nanochannel to stretch is restrictedly translocates in the length direction. Current is measured to determine an identity of the single base.

  • Publication number: 20140147833
    Abstract: A mechanism is provided for base recognition in a nanopore detection system. A complex including a long chain polynucleotide and a motor molecule is formed. The complex is localized in a nanopore of the nanopore detection system. A conformation change of the motor molecule is detected while localized in the nanopore by an ionic current having an amplitude and duration time. The detected conformation change includes the motor molecule forming a base pair by incorporating a single base of the long chain polynucleotide and by synthesizing a complementary base of the single base. An identity of the single base of the long change polynucleotide is determined from the amplitude and the duration time of the conformation change of the motor molecule for the base pair.
