Figure 8.

The real part of CM factor as a function of electric field frequency for live (red line) and dead (blue line) yeast cells at medium conductivity of 140 μS/cm. Positive value of real part of CM factor represents yeast cells under positive DEP, while the negative value represents cells under negative DEP. The violet dashed line indicates the working frequency for separating them due to the difference in DEP forces. The inset is the optical microscope image of mixture of live and dead yeast cells dyed by two colors.
