  • Methods and apparatus for electrosmear analysis
    Patent number: 7862702
    Abstract: Methods and apparatus for preparing a smear for cytopathology or other analysis. In a representative embodiment, cells of a sample are subjected to a dielectrophoretic force to segregate the cells into two or more zones of a surface. The particles are attached to the surface, thereby defining a “segregated smear.” The segregated smear is then fixed and stained for cytopathology analysis.
    Type: Grant
    Filed: July 24, 2006
    Date of Patent: January 4, 2011
    Assignee: Board of Regents, The University of Texas System
    Inventors: Peter R. C. Gascoyne, Jody V. Vykoukal, Chandra Das, Frederick F. Becker
