Publication number: 20210178403Abstract: The invention features devices and methods for the deterministic separation of particles. Exemplary methods include the enrichment of a sample in a desired particle or the alteration of a desired particle in the device. The devices and methods are advantageously employed to enrich for rare cells, e.g., fetal cells, present in a sample, e.g., maternal blood and rare cell components, e.g., fetal cell nuclei. The invention further provides a method for preferentially lysing cells of interest in a sample, e.g., to extract clinical information from a cellular component, e.g., a nucleus, of the cells of interest. In general, the method employs differential lysis between the cells of interest and other cells (e.g., other nucleated cells) in the sample.Type: ApplicationFiled: September 15, 2020Publication date: June 17, 2021Inventors: Lotien Richard Huang, Thomas A.

Patent number: 7597791Abstract: A method and apparatus for generating tunable, uniform electric fields in fluidic applications for rapid separation of molecules, such as DNA, is provided. A region receives the molecules to be separated, the molecules being injected into the region by an injection channel connected thereto. Fluidic microchannels or resistor arrays connected to sides of the region inject currents into the region and produce electric fields in the region that can be oriented at any angle. The electric fields can separate the molecules according to size, and can be used to move or manipulate the molecules within the region. Further, the molecules can be separated by controlling fluid flows within the region to manipulate the molecules. One or more reservoirs can be attached to the fluidic microchannels for collecting the molecules after separation, movement, or manipulation.Type: GrantFiled: May 15, 2002Date of Patent: October 6, 2009Assignee: The Trustees of Princeton UniversityInventors: Lotien Richard Huang, James Christopher Sturm, Robert Hamilton Austin

Publication number: 20090014332Abstract: A method and apparatus for fractionation of charged macro-molecules such as DNA is provided. DNA solution is loaded into a matrix including an array of obstacles. An alternating electric field having two different fields at different orientations is applied. The alternating electric field is asymmetric in that one field is stronger in duration or intensity than the other field, or is otherwise asymmetric. The DNA molecules are thereby fractionated according to site and are driven to a far side of the matrix where the fractionated DNA is recovered. The fractionating electric field can be used to load and recover the DNA to operate the process continuously.Type: ApplicationFiled: July 29, 2008Publication date: January 15, 2009Inventors: Lotien Richard Huang, James Christopher Sturm, Robert Hamilton Austin
