Title
(EN) REUSABLE BIOSENSOR PLATFORM
(FR) PLATE-FORME DE BIOCAPTEUR RÉUTILISABLE
Abstract
(EN)
Techniques, apparatus and systems are described for generating reusable and reconfigurable biosensors. A microfluidic device includes a substrate layer and an electrode layer disposed above the substrate layer. A spacer layer is disposed above the electrode layers to form at least two channels. Another electrode layer is disposed above the spacer layer. Also, another substrate layer is disposed above the other electrode layer. The other substrate layer can include at least two inlets, each connected to one of the at least two channels, two outlets corresponding to the two inlets, and two electrical contacts filled with a conductive material to form a conductive feedthrough to the other electrode layer.

L'invention concerne des techniques, un appareil et des systèmes destinés à générer des biocapteurs réutilisables et reconfigurables. Un dispositif microfluidique comprend une couche substrat, et une couche électrode disposée au-dessus de la couche substrat. Une couche d'espacement est disposée au-dessus des couches électrodes pour former au moins deux canaux. Une autre couche électrode est disposée au-dessus de la couche d'espacement. Une autre couche substrat est également disposée au-dessus de l'autre couche électrode. L'autre couche substrat comprend au moins deux entrées, chacune étant reliée à l'un des deux canaux, deux sorties correspondant aux entrées, et deux contacts électriques remplis d'un matériau conducteur pour former feedthrough conducteur vers l'autre couche électrode.
