Cell Electrical Impedance as a Novel Approach for Studies on Senescence Not Based on Biomarkers

Figure 5

(a) Comparison of magnitudes at the optimal frequency (1 MHz) among the three age groups. Vertical bars represent standard error. (b) Comparison of phase angles at the optimal frequency (30 kHz) among the three age groups. Vertical bars represent standard error. (c) Distribution of the magnitude at 1 MHz versus the phase angle at 30 kHz for 30 cells from each group.
