  • System and method for precision transport, positioning, and assembling of longitudinal nano-structures
    Patent number: 9044808
    Abstract: A method for assembling multi-component nano-structures that includes dispersing a plurality of nano-structures in a fluid medium, and applying an electric field having an alternating current (AC) component and a direct current (DC) component to the fluid medium containing the plurality of nano-structures. The electric field causes a first nano-structure from the plurality of nano-structures to move to a predetermined position and orientation relative to a second nano-structure of the plurality of nano-structures such that the first and second nano-structures assemble into a multi-component nano-structure.
    Type: Grant
    Filed: March 3, 2010
    Date of Patent: June 2, 2015
    Assignee: The Johns Hopkins University
    Inventors: Chia-Ling Chien, Donglei Fan, Robert Charles Cammarata
