Impedance response of live and dead algal cells. (a) Average cell transparency calculated using peak intensity measured at 20 MHz over peak intensity measured at 500 kHz. (b) The impedance scatter of live and dead algal cells. The x-axis shows the peak intensity at 500 kHz, which indicates cell size. The y-axis shows the peak intensity at 20 MHz, which indicates algal cytoplasmic permeability. (c) Average impedance frequency response of live and dead algal cells. The impedance responses were measured at 500 kHz, 20 MHz, 25 MHz, and 30 MHz.
