Abstract

A method is described for non-destructive measurement of vitality of biological cells, especially for determination of apoptosis, in which the at least one cell is exposed to high-frequency alternating, especially rotating, electric fields and/or impedance test fields, and at least one rotation measurement, one dielectrophoresis measurement and/or one impedance measurement is performed with the cell for at least one frequency range or individual frequencies, from which at least one measurement parameter is determined that is characteristic of the vitality state of the cell.
