  • CELL SORTING SYSTEM AND METHODS
    Publication number: 20150024476
    Abstract: Apparatus and Methods are provided for a microfabricated fluorescence activated cell sorter based on a switch for rapid, active control of cell routing through a microfluidic channel network. This sorter enables low-stress, highly efficient sorting of populations of small numbers of cells (i.e., 1000-100,000 cells). The invention includes packaging of the microfluidic channel network in a self-contained plastic cartridge that enables microfluidic channel network to macro-scale instrument interconnect, in a sterile, disposable format. Optical and/or fluidic switching forces are used alone or in combination to effect switching.

  • Separation and Manipulation of a Chiral Object
    Publication number: 20140209464
    Abstract: Among other things, for use in directional motion of chiral objects in a mixture, a field is applied across the chamber and is rotating relative to the chamber to cause rotation of the chiral objects. The rotation of the objects causes them to move directionally based on their chirality. The method applies to sugars, proteins, and peptides, among other things, and can be used in a wide variety of applications.
