Abstract: The invention concerns an apparatus (10) comprising essentially a support (11) wherein is placed a measuring card (12), a perfusion device (13), a thermostat (14), a measuring box (15) and a measurement management system (16). The measuring card (12) comprises an electrode array whereof one end emerges into the chamber and the other end is placed outside said chamber. The group of cells is placed in the chamber which is connected to the perfusion device (13). The support (11) comprises a connector (25) connecting the card (12) electrodes to the measurement management system (16) via the measuring box (15).

Abstract: The invention concerns a device comprising a support (11) in the thickness of which is produced a supply chamber (12) with an inlet duct (13) for nutrient liquid and a discharge duct (14) for said liquid. A capsule (22) capable of receiving organic cells is provided on the support (11). The supply chamber (12) and the support (11) are separated by a porous membrane (16) comprising an array of electrodes (17) arranged so as to be in contact with different zones of the group of cells, thereby enabling their electrophysiological activity to be analyzed. The device enables to increase the life span of cells and to carry out analyses simply and without affecting the cell organization.
