    • 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).
    • 首先,对作为测量对象的单元的形状进行建模,通过数值分析获得AC电场施加到电池的复电介质响应(步骤S1)。 基于该结果进行数值计算,同时改变膜电容Cm和细胞质电导率k的值,从而计算电介质谱(步骤S2)。 这样计算的电介质光谱与介电弛豫表达式相反,从而获得上升和下降。 相对电容率和弛豫时间τ(步骤S3)。 接下来,获得(&Dgr;&egr;τ)对(Cm,&kgr; i)的依赖性,由此创建与作为测量对象的单元格的形状相对应的回归表达式(步骤S4)。 实际测量细胞的介电光谱,并将所得值实际测量并且将回归表达式彼此进行比较,从而获得细胞的膜电容Cm,exp和细胞胞质电导率&kgr; i,exp作为 测量对象(步骤5)。

    • 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.
