DEVICE FOR DERIVING ELECTROPHYSIOLOGICAL SIGNALS FROM CELLS

摘要

The invention relates to a device for deriving electrophysiological signals from cells, comprising a layer structure that comprises a substrate and an electrode arranged on the substrate for deriving the signals by means of a strip conductor (L) connected to the electrode, the layer structure being passivated by a passivation layer, characterized in that the passivation layer has an aperture (21) extending through the passivation layer above the electrode, and a gap (22) is arranged between the electrode and the passivation layer as a lateral undercut. The invention further relates to a method for producing the device and to a use of the device produced in this way.
