  • Method and apparatus for manipulating particles
    Patent number: 10350613
    Abstract: A method and apparatus for manipulating polarizable dielectric particles. The method includes positioning a liquid containing the particles above a surface of a piezoelectric material (2). The method also includes inducing a shear-horizontal surface acoustic wave in the piezoelectric material (2), thereby to form a time-varying non-uniform evanescent electric field extending into the liquid. The method further includes using the time-varying non-uniform evanescent electric field to apply a force to at least some of the particles (50, 52) by dielectrophoresis.
    Type: Grant
    Filed: May 8, 2014
    Date of Patent: July 16, 2019
    Assignee: UNIVERSITY OF LEEDS
    Inventors: Christoph Walti, Alban Josiah Smith, Richard O'Rorke, Alexander Giles Davies, Christopher David Wood
