Publication number: 20150017678Abstract: Embodiments are generally related to differentiating and/or separating portions of a sample that are of interest from the remainder of the sample. Embodiments may be directed towards separating cells of interest from a cell sample. In some embodiments, acoustic impedances of the cells of interest may be modified. For example, the acoustic properties of the cells of interest may be modified by attaching bubbles to the cells of interest. The cell sample may then be subjected to an acoustic wave. The cells of interest may be differentiated and/or separated from the remainder of the sample based on relative displacements and/or volumetric changes experienced by the cells of interest in response thereto. The cells of interest may be separated using a standing wave and sorted into separate channels of a flow cell. Optionally, the cells may be interrogated by a light source and differentiated by signals generated in response thereto.Type: ApplicationFiled: April 16, 2014Publication date: January 15, 2015Applicant: University of Washington Through Its Center for CommercializationInventors: Thomas Matula, Andrew A.

Patent number: 8932874Abstract: The invention is directed towards methods and compositions for identifying the amount of ammonium acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of ammonium acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of ammonium acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the ammonium acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.Type: GrantFiled: July 2, 2014Date of Patent: January 13, 2015Assignee: Nalco CompanyInventors: Amy M. Tseng, Brian V. Jenkins, Robert M. Mack

Publication number: 20150004620Abstract: A method of identifying inhibitors of epithelial-mesenchymal transition (EMT). The method may comprise comparing different sets of image data obtained from one or more cell colonies before (T1) and after (T2) exposure to a possible inhibitor of epithelial-mesenchymal transition. The method may further comprise measuring the cell number and a spreading coefficient value in the one or more cell colonies for determining cell count ratio (CCR) and normalized cell dispersion ratio (CDR) for the one or more colonies. The possible inhibitor may then be identified to be an inhibitor of EMT if the determined CCR and CDR indicates that the possible inhibitor i) does not or marginally inhibit growth and inhibits EMT, or ii) inhibits growth and inhibits cell dispersion and optionally inhibits also EMT, or iii) is cytotoxic and inhibits cell dispersion and optionally inhibits also EMT.Type: ApplicationFiled: December 28, 2012Publication date: January 1, 2015Inventors: Jean Paul Thiery, Kian Nigiap Chuo, Wen Jing Sim
