  • Droplet compartmentalization for chemical separation and on-line sampling
    Patent number: 8062903
    Abstract: Methods and devices are provided for overcoming detrimental diffusive effects in a sample liquid stream by forming segmented liquid bodies (e.g., droplets) from a sample liquid stream in an immiscible liquid stream. The liquid bodies are formed at the intersection of a channel providing the sample liquid stream and a channel providing the immiscible liquid stream. The formed liquid bodies compartmentalize the portion of the sample liquid stream from which the liquid bodies are formed, thus minimizing the detrimental effects of diffusion that occur in a continuous liquid stream.
    Type: Grant
    Filed: March 3, 2009
    Date of Patent: November 22, 2011
    Assignee: University of Washington
    Inventors: Daniel T. Chiu, John Scott Edgar
  • Method and device for biochemical detection and analysis of subcellular compartments from a single cell
    Patent number: 7767435
    Abstract: A method and system for performing biochemical detection or analysis on micro- and nano-scale subcellular component within a single biological cell is provided. An integrated platform device and method to perform the biochemical analysis is also provided.
