Abstract: The arrangement for supercapacitor device comprises an electrode (1) provided with an electrically conductive element (4). It also comprises a separator element (3) fixed against a first face (4a) of the electrically conductive element (4), the arrangement being perforated with a plurality of through holes (5) which pass through both the electrically conductive element (4) and the separator element (3). The perforated separator element (3) forms a membrane that is both electrically insulating and porous to ions of an electrolyte of the supercapacitor device. The electrically conductive element (4) of the electrode (1) being perforated, the equivalent surface area of the electrodes of the supercapacitor device is dependent on the number of holes made and on their depth.

Abstract: The present invention concerns a method for detecting a molecular recognition by electrochemiluminescence. Said method comprises the steps consisting in a) depositing an electronically conductive film on a support and attaching on said film a sensor molecule in order to obtain a test support; b) subjecting the sample to be tested to a protocol of marking the target molecule with an electrochemiluminescent marker; c) bringing the marked target into contact with the test support; d) rinsing the test support; and e) subjecting the test support rinsed in step d) to a reading of the electrochemiluminescence signal triggered by a direct, or indirect, electronic transfer between the target and the support via the electronically conductive film.
