Abstract
Disclosed herein is a dielectric cytometric apparatus capable of analyzing cells and sorting the cells without adopting an optical analysis method and provides a dielectric cytometric cell sorting method for the apparatus. A stenosis channel allowing a single cell to flow is created on a cell injection section of a micro flow channel device used as a portion of the dielectric cytometric apparatus. A pair of measurement electrodes is created on the stenosis channel and an analyzer connected to the measurement electrodes measures the complex dielectric constant of for every cell passing through the stenosis channel. A electric-field application section provided on the downstream side of the stenosis channel applies an electric field for changing the flow of the cells inside a flow channel on the basis of information on the measured complex dielectric constants so that the cells can be sorted by making use of branch channels.
