    摘要: The invention relates to an electrode assembly 20, in particular for applying at least one electric field to adherent cells, comprising at least two electrodes 21, each having at least one surface 32 which is arranged opposite the corresponding surface 32 of the other electrode 21, wherein an electrically insulating material 26 is arranged at least partially between the surfaces 32 of the electrodes 21. 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.

    摘要: The invention relates to a device (1) for applying an electric field to a suspension of cells, cell derivatives, organelles, sub-cellular particles and/or vesicles, comprising at least one chamber (6) which comprises at least two electrodes (4), and at least one separating element (13) which is movable within the chamber (6) between two terminal points (14, 15) and, if it is in a position between the terminal points (14, 15), separates at least one first compartment (26) of the chamber (6) from at least one second compartment (27) of the chamber (6). According to the invention each compartment (26, 27) is designed to hold the suspension and comprises at least one port (7, 8, 10, 11) for charging or discharging the suspension, so as to discharge an aliquot of the suspension from the chamber (6) and at the same time charge a further aliquot of the suspension into the chamber (6), wherein the separating element (13) is moved in a second direction opposite to a first direction, and wherein the separating element (13) separates the aliquots from each other.

    摘要: Disclosed is a device for applying an electric field to a suspension of cells, comprising at least one chamber which comprises at least one internal space (40) for holding the suspension, the internal space (40) comprising at least two segments (41, 42), wherein each segment (41, 42) comprises at least one electrode (43, 44) and wherein neighboring electrodes (43, 44) are separated from each other by at least one gap (47) which is at least partially filled with an insulating material (46), and wherein the edges of the electrodes (43, 44) facing each other within the internal space (40) are rounded. Rounding the electrodes' edges facing a neighboring electrode results in a significant reduction of field gradients and thus even of the risk of arcing. Also disclosed is a method in which voltage is applied to at least one active electrode (43, 44) while the electrodes (43, 44, 45) or electrode segments next and/or opposite to the active electrode (43, 44) are set to ground potential. Setting neighboring electrodes that surround the active electrode to ground potential results in decreased scattering of the electric field within the internal space so that the electrically active area is locally limited and the field lines are focused near the active electrode and thus control of the process is enhanced.

    摘要: The invention relates to a method for subjecting adherent cells to at least one electric field, in which the electric field is generated by applying a voltage to at least two active electrodes 63, wherein at least three electrodes 63, 64 are provided, and wherein at least two electrodes 63, 64 are active electrodes 63 when the voltage is applied in order to generate a first electric field, and in which at least one second electric field is generated, wherein at least one of the two previously active electrodes 63 is a potential-free electrode 64 when the voltage is applied. The invention further relates to a device 58 comprising at least three electrodes 63, 64, which are connected to at least one voltage source by means of at least one switching device 59, 60, 61, 62, wherein at least five electrodes 63, 64 are connected to the at least one voltage source by means of four switching devices 59, 60, 61, 62, wherein at least two electrodes 63, 64 are connected to the voltage source by means of a common switching device 59, 60, 61, 62. In conjunction with the method described above, the device according to the invention allows the efficient and uniform treatment of adherent cells using an electric field, wherein the switch between active and potential-free electrodes can be carried out quickly and safely using a lower number of switching devices.
