Abstract

The invention relates to an electrode assembly (10) for electrophysiologically analyzing biological cells (Z) and similar. Said electrode assembly (10) comprises a contact zone (40k) for contacting the electrode assembly (10) with a biological cell (Z) or similar, and a connecting zone (40A) for electrically contacting the electrode assembly (10) externally. The contact zone (40K) is embodied with one or a plurality of electrode tips (40s) which extend from the connecting zone (40a) and are provided with a geometrical shape that allows for an otherwise non-destructive invasion into the interior (I) of a biological cell (Z) or similar via the membrane (M) thereof during operation of the electrode assembly.
