Determination of the adhesion process and progression of the resistance of cells on ECIS arrays with time. (A) The adhesion process can be determined by application of the frequency (f > 40 kHz). (B) By application of a frequency (f < 400 Hz) the development of cell-cell contacts (tight junctions) can be monitored. Bold arrow indicates the small fluctuations on the electrode due to micro motion in the cell monolayers. From [31] with permission.
