Patent number: 8795497Abstract: Disclosed herein is a cell sorter including a measuring electrode, working electrode, detection electrode, and output section. The measuring electrode forms a measuring electric field in a flow path to measure a complex dielectric constant of each cells flowing through the flow path. The working electrode forms, in the flow path, a working electric field to sort the cells by imparting a dielectrophoretic force to the cells and using the flow path. The detection electrode detects the presence of the cell in the fluid flowing through the flow path. The output section acquires a sorting signal based on information about the measured complex dielectric constant and a detection signal indicating the detection of the cell by the detection electrode. The output section outputs a working signal adapted to form the working electric field to the working electrode when the detection signal is acquired if the sorting signal is acquired.Type: GrantFiled: October 13, 2011Date of Patent: August 5, 2014Assignee: Sony CorporationInventors: Kazumasa Sato, Yoichi Katsumoto
