Abstract
The invention relates to an electrode assembly, in particular for applying at least one electric field to adherent cells, comprising at least two electrodes, each having at least one surfacewhich is arranged opposite the corresponding surfaceof the other electrode, wherein an electrically insulating materialis arranged at least partially between the surfacesof the electrodes. The solution according to the invention allows the electric field to be concentrated in the region of the cells to be treated such that a voltage pulse, or the current produced thereby, flows through the cells without the majority flowing away over the cells unused in the electrolyte. The invention further relates to a method for applying at least one electric field to adherent cells, in which the electric field is generated by applying a voltage to at least two electrodes, the electric field is concentrated on the side of the electrodes which faces the cells and/or is limited to the space between the cells and the side of the electrodes which faces the cells.
