    • Direct haplotyping of kilobase-size DNA using carbon nanotube probes 

      Woolley, Adam T.; Guillemette, Chantal; Cheung, Chin Li; Housman, David E.; Lieber, Charles (Nature Publishing Group, 2000)
      We have implemented a method for multiplexed detection of polymorphic sites and direct determination of haplotypes in 10-kilobase- size DNA fragments using single-walled carbon nanotube (SWNT) atomic force microscopy ...

    • Growth and fabrication with single-walled carbon nanotube probe microscopy tips 

      Cheung, Chin Li; Lieber, Charles; Odom, Teri W.; Hafner, Jason H.; Kim, Kyoungha (American Institute of Physics, 2000)
      Single-walled carbon nanotube (SWNT) probe microscopy tips were grown by a surface growth chemical vapor deposition method. Tips consisting of individual SWNTs (1.5–4 nm in diameter) and SWNT bundles (4–12 nm in diameter) ...

    • Ion Induced Changes in the Structure of Bordered Pit Membranes 

      Lee, Jinkee; Holbrook, Noel Michele; Zwieniecki, Maciej A. (Frontiers Research Foundation, 2012)
      Ion-mediated changes in xylem hydraulic resistance are hypothesized to result from hydrogel like properties of pectins located in the bordered pit membranes separating adjacent xylem vessels. Although the kinetics of the ...

    • Kinetic Energy Effects on Morphology Evolution During Pulsed Laser Deposition of Metal-On-Insulator Films 

      Warrender, Jeffrey M.; Aziz, Michael (American Physical Society, 2007)
      We report an experimental comparison of Volmer-Weber metal-on-insulator growth morphology in pulsed laser deposition (PLD) and thermal deposition under identical thermal, background, and surface preparation conditions for ...

    • Microcantilever Q Control Via Capacitive Coupling 

      Huefner, Magdalena; Pivonka, Adam; Kim, Jeehoon; Ye, Cun; Blood-Forsythe, Martin Ashby; Zech, Martin; Hoffman, Jenny Eve (American Institute of Physics, 2012)
      We introduce a versatile method to control the quality factor Q of a conducting cantilever in an atomic force microscope (AFM) via capacitive coupling to the local environment. Using this method, Q may be reversibly tuned ...

    • Structural and Functional Imaging with Carbon Nanotube AFM Probes 

      Hafner, Jason H.; Cheung, Chin Li; Wooley, Adam T.; Lieber, Charles (Pergamon Press, 2001)
      Atomic force microscopy (AFM) has great potential as a tool for structural biology, a field in which there is increasing demand to characterize larger and more complex biomolecular systems. However, the poorly characterized ...

    • Structural Biology with Carbon Nanotube AFM Probes 

      Hafner, Jason H.; Woolley, Adam T.; Cheung, Chin Li; Lieber, Charles (Current Biology Ltd., 2000)
      Carbon nanotubes represent ideal probes for high-resolution structural and chemical imaging of biomolecules with atomic force microscopy. Recent advances in fabrication of carbon nanotube probes with sub-nanometer radii ...
