Stephan K. W. Dertinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for gradient generation
    Patent number: 7314070
    Abstract: A method and apparatus for treating a fluid. A method for treating a fluid may include combining two or more separate streams into a common stream and then splitting the common stream into a new set of separate streams wherein the separate streams may possess different properties. The separate streams may be combined to produce a gradient, such as a concentration gradient or shear gradient. The apparatus of the invention may provide a network of fluidic channels that may be used to manipulate a fluid to produce, for example, a gradient or a series of solutions containing a substance at varying concentrations.
    Type: Grant
    Filed: January 18, 2005
    Date of Patent: January 1, 2008
    Assignee: President and Fellows of Harvard College
    Inventors: Noo Li Jeon, Stephan K. W. Dertinger, Daniel T. Chiu, Insung S. Choi, George M. Whitesides
