| 20090041949 | Patterning by energetically-stimulated local removal of solid-condensed-gas layers and solid state chemical reactions produced with such layers - The invention provides a method for forming a patterned material layer on a structure, by condensing a vapor to a solid condensate layer on a surface of the structure and then localized removal of selected regions of the condensate layer by directing a beam of energy at the selected regions. The structure can then be processed, with at least a portion of the patterned solid condensate layer on the structure surface, and then the solid condensate layer removed. Further there can be stimulated localized reaction between the solid condensate layer and the structure by directing a beam of energy at at least one selected region of the condensate layer. | 02-12-2009 |

| 20090136682 | Carbon nanotube synthesis for nanopore devices - In a process for fabricating a nanopore device, at least one carbon nanotube catalyst region is formed on a structure. A plurality of nanopores is formed in the structure at a distance from the catalyst region that is no greater than about an expected length for a carbon nanotube synthesized from the catalyst region. Then at least one carbon nanotube is synthesized from the catalyst region. This fabrication sequence enables the in situ synthesis of carbon nanotubes at the site of nanopores, whereby one or more nanotubes articulate one or more nanopores without requiring manual positioning of the nanotubes. | 05-28-2009 |
| 20090136958 | Capture, recapture, and trapping of molecules with a nanopore - In a molecular analysis system, there is provided a structure including a nanopore and first and second fluidic reservoirs. The two reservoirs are fluidically connected via the nanopore. A detector is connected to detect molecular species translocation of the nanopore, from one of the two fluidic reservoirs to the other of the two fluidic reservoirs. A controller is connected to generate a control signal to produce conditions at the nanopore to induce the molecular species to re-translocate the nanopore at least once after translocating the nanopore. This enables a method for molecular analysis in which a molecular species is translocated a plurality of times through a nanopore in a structure between two fluidic reservoirs separated by the structure. | 05-28-2009 |
| 20090173716 | Lift-off patterning processes employing energetically-stimulated local removal of solid-condensed-gas layers - The invention provides a method for forming a patterned material layer on a structure, by condensing a vapor to a solid condensate layer on a surface of the structure and then localized removal of selected regions of the condensate layer by directing an ion beam at the selected regions, exposing the structure at the selected regions. A material layer is then deposited on top of the solid condensate layer and the exposed structure at the selected regions. Then the solid condensate layer and regions of the material layer that were deposited on the solid condensate layer are removed, leaving a patterned material layer on the structure. | 07-09-2009 |
| 20090179005 | Nanotube Processing Employing Solid-Condensed-Gas-Layers - In a method for processing a nanotube, a vapor is condensed to a solid condensate layer on a surface of the nanotube and then at least one selected region of the condensate layer is locally removed by directing a beam of energy at the selected region. The nanotube can be processed with at least a portion of the solid condensate layer maintained on the nanotube surface and thereafter the solid condensate layer removed. Nanotube processing can include, e.g., depositing a material layer on an exposed nanotube surface region where the condensate layer was removed. After forming a solid condensate layer, an electron beam can be directed at a selected region along a nanotube length corresponding to a location for cutting the nanotube, to locally remove the condensate layer at the region, and an ion beam can be directed at the selected region to cut the nanotube at the selected region. | 07-16-2009 |
| 20110155574 | Molecular Characterization with Molecular Speed Control - Provided is a first reservoir for containing a liquid solution including a molecule to be characterized and a second reservoir for containing a liquid solution. A solid state support includes a nanopore having a molecular inlet providing a fluidic connection to the first reservoir and a molecular outlet providing a fluidic connection to the second reservoir. An electrical connection is disposed between the first and second reservoirs to apply a molecular translocation voltage across the nanopore between the molecular inlet entrance and outlet exit. At least one electrical probe is disposed at the nanopore to apply a first voltage bias with respect to translocation voltage to slow progression of a molecule through the nanopore between the molecular inlet and outlet and to apply a second voltage bias with respect to translocation voltage to cause the molecule to proceed through the nanopore between the molecular inlet and outlet. | 06-30-2011 |

The methods employ a nanopore which the polymer, e.g., a nucleic acid, traverses. As the polymer traverses the nanopore, measurements of transport properties of the nanopore yield data on the conformation of the polymer. | 06-30-2011 |
