The Variation of Harmonics for Difference of Electrode Materials in Nonlinear Dielectric Properties on Yeast Cells

Abstract

When ac voltage is applied to cell suspensions, response waves analyzed using FFT show the appearance of third harmonics for resting cells and fourth harmonics for active cells. For studying the relationship between electrodes and cells, we examined the appearance of harmonics patterns in electrodes of different materials. The results showed that there were different harmonics patterns between electrode materials. We regard that such particular harmonics patterns derive from the correlation between electrodes and cells.
