  • Publication number: 20070009909
    Abstract: A method is described that involves sorting CNT hybrid structures of differing sizes by passing the CNT hybrid structures through an arrangement of fixed structures. The sorting involves a diffusion component in which shorter CNT hybrid structures are scattered through the arrangement of fixed structures to a greater degree than at which longer CNT hybrid structures are scattered through the arrangement of fixed structures.

  • Publication number: 20060133952
    Abstract: Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response.

  • Publication number: 20060070920
    Abstract: A method is described that comprises sorting carbon nanotubes (CNTs) within a fluidic flow for a targeted subset of the CNTs. The sorting comprises attracting at least a portion of the CNTs within the fluidic flow in a direction of increasing intensity of an electric field component of a substantially stationary beam of light. The electric field component has a frequency that is less than one or more resonant frequencies of the CNTs within the portion.

  • Patent number: 6974926
    Abstract: In embodiments of the present invention, the electric field of a focused laser beam induces a dipole in a single-walled carbon nanotube. The single-walled carbon nanotube has one or more resonant frequencies. When the frequency of the laser beam is less than a resonance frequency of the single-walled carbon nanotube, the single-walled carbon nanotube may be trapped and the laser beam may move the single-walled carbon nanotube from a first microfluidic laminar flow to a second microfluidic laminar flow. When the frequency of the laser beam is higher than a resonant frequency of the single-walled carbon nanotube, the single-walled carbon nanotube may be repelled and the laser beam may not move the single-walled carbon nanotube.

  • Patent number: 6972467
    Abstract: According to one aspect of the invention, a semiconducting transistor is described. The channel portion of the transistor includes carbon nanotubes formed on top of an insulating layer which covers a local bottom gate. Source and drain conductors are located at ends of the carbon nanotubes. A gate dielectric surrounds a portion of the carbon nanotubes with a substantially uniform thickness. A local top gate is located between the source and drain conductors over the carbon nanotubes. Lower portions of the local top gate are positioned between the carbon nanotubes as the local top gate forms pi-gates or “wraparound” gates around each carbon nanotube.

  • Publication number: 20050221333
    Abstract: Disclosed herein are methods, apparatuses, and systems for performing nucleic acid sequencing reactions and molecular binding reactions in a microfluidic channel. The methods, apparatuses, and systems can include a restriction barrier to restrict movement of a particle to which a nucleic acid is attached. Furthermore, the methods, apparatuses, and systems can include hydrodynamic focusing of a delivery flow. In addition, the methods, apparatuses, and systems can reduce non-specific interaction with a surface of the microfluidic channel by providing a protective flow between the surface and a delivery flow.
