  • Microfluidic apparatus and method for enriching and analyzing biological cells
    Publication number: 20030224436
    Abstract: Integrated microfluidic devices comprising at least an enrichment channel (10) and a main electrophoretic flowpath (12) are provided. In the subject integrated devices, the enrichment channel and the main electrophoretic flowpath are positioned so that waste fluid flows away from said main electrophoretic flowpath through a discharge outlet (6). The subject devices find use in a variety of electrophoretic applications, including clinical assays, high throughput screening for genomics and pharmaceutical applications, point-or-care in vitro diagnostics, molecular genetic analysis and nucleic acid diagnostics, cell separations, and bioresearch generally.
    Type: Application
    Filed: May 16, 2003
    Publication date: December 4, 2003
    Inventors: Robert J. Nelson, Herbert H. Hooper, Alan K. Hauser, Sharat Singh, Stephen J. Williams, Alexander P. Sassi
