摘要： Firstly, a shape of a cell as an object of a measurement is modeled, and a complex electric permittivity response when an AC electric field is applied to the cell is obtained through a numerical analysis (Step S1). A numerical calculation is carried out based on that result while values of a membrane capacitance Cm and a cell cytoplasm electric conductivity κi are changed, thereby calculating a dielectric spectrum (Step S2). The dielectric spectrum thus calculated is revolved to a dielectric relaxation expression, thereby obtaining a rise Δε in relative electric permittivity and relaxation time τ (Step S3). Next, dependency of (Δε, τ) on (Cm, κi) is obtained, thereby creating a regression expression corresponding to the shape of the cell as the object of the measurement (Step S4). A dielectric spectrum of the cell is actually measured, and the resulting values actually measured and the regression expression are compared with each other, thereby obtaining a membrane capacitance Cm, exp and a cell cytoplasm electric conductivity κi, exp of the cell as the object of the measurement (Step 5).

摘要： A flow channel device, a complex permittivity measuring apparatus, and a dielectric cytometry system are provided which can improve the measurement accuracy. A constriction portion having a constricted space is disposed between an inflow port and an outflow port of a flow channel. Electrodes are arranged between the inflow port and the constriction portion and between the outflow port and the constriction portion. The conductance of the constriction portion at a low-limit frequency is less than the combined conductance of an inflow channel portion and an outflow channel portion. The capacitance of the constriction portion at a high-limit frequency is less than the combined capacitance of the inflow channel portion and the outflow channel portion.

摘要： 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.
