  • Microfluidic magnetophoretic device and methods for using the same
    Patent number: 8071054
    Abstract: A microfluidic device may employ one or more sorting stations for separating target species from other species in a sample. The separation is driven by magnetophoresis. A sorting station generally includes separate buffer and sample streams. A magnetic field gradient applied to the sorting station deflects the flow path of magnetic particles (which selectively label the target species) from a sample stream into a buffer stream. The buffer stream leaving the sorting station is used to detect or further process purified target species labeled with the magnetic particles.
    Type: Grant
    Filed: August 30, 2010
    Date of Patent: December 6, 2011
    Assignee: The Regents of the University of California
    Inventors: Sang-Hyun Oh, Amarendra Kumar Singh, Yanting Zhang, Dharmakirthi Nawarathna, Unyoung Kim, Patrick Sean Daugherty, Hyongsok Soh, Brian Scott Ferguson
