Dielectrophoresis: A Review of Applications for Stem Cell Research
Figure 1
The DEP response exhibited by a viable cell under typical experimental conditions is often of the form shown here. The DEP force reverses polarity at two DEP cross-over frequencies, and , determined by the various cell parameters listed in this figure. As indicated by (4), determination of and cell diameter, along with the conductivity of the suspending solution, provides a measure of cell membrane capacitance. As yet, direct measurements of have not been reported.
