ABSTRACT:
Described are methods for electrical treatment of biological cells, in particular using electrical field pulses, involving the steps: arrangement of the cells (1) on apertures (2) of a solid planar carrier element (3) which divides a measuring chamber (10) into two compartments (11, 12); and temporary formation of an electrical treatment field which permeates the cells, wherein an alternating-current impedance measurement takes place on the carrier element (3), and from the result of the alternating-current impedance measurement, a degree of coverage of the carrier element and/or healing of the cells after electrical treatment are/is acquired. Also described are devices for implementing the methods.
