Title (EN) MICROFLUIDIC DEVICE WITH LATERALLY INSERTABLE ELECTRODES
(FR) DISPOSITIF MICROFLUIDIQUE AVEC ÉLECTRODES POUVANT ÊTRE INSÉRÉES LATÉRALEMENT
Abstract:
(EN) The invention is notably directed to a microfluidic device. The device comprises a substrate with a microchannel formed as a groove on a main surface of the substrate. The device further comprises one or more conduits extending parallel to the main surface of the substrate, and from a lateral surface of the substrate up to a lateral wall of the microchannel. The one or more conduits are configured so as to allow insertion of one or more electrodes therein, respectively, and such that an end of each of the one or more electrodes can reach into the microchannel. The invention is further directed to related sets of components, which include the above microfluidic device, as well as a housing, with electronics, and, possibly, a porous support (e.g., a membrane) and a cap. Biosensing applications are notably contemplated. The invention is further directed to methods of operating a microfluidic device.
(FR) L'invention concerne un dispositif microfluidique. Le dispositif comprend un substrat avec un microcanal formé sous la forme d'une rainure sur une surface principale du substrat. Le dispositif comprend en outre un ou plusieurs conduits s'étendant parallèlement à la surface principale du substrat, et à partir d'une surface latérale du substrat jusqu'à une paroi latérale du microcanal. Le ou les conduits sont conçus de façon à permettre l'insertion d'une ou de plusieurs électrodes en leur intérieur, respectivement, et de telle sorte qu'une extrémité de chacune de la ou des électrodes peut atteindre l'intérieur du microcanal. L'invention concerne en outre des ensembles associés de composants, qui comprennent le dispositif microfluidique ci-dessus, ainsi qu'un boîtier, avec des composants électroniques, et, éventuellement, un support poreux (par exemple, une membrane) et un capuchon. Des applications de biodétection sont notamment envisagées. L'invention concerne en outre des procédés d'exploitation d'un dispositif microfluidique.
