Patent ID: 8096322

Claim:
A microfluidic device comprising a first plate forming a substrate and including one or more perforations and, on each side of the first plate, at more than one location, a material that is adapted to define passage portions and is formed, at one or more of these locations, of an activatable material, the volume of which can be varied by activating it, said material being arranged at said locations in such a way that, in a first phase, by activating one or more locations consisting of said activatable material, a first configuration is transformed into a second configuration, which modifies a three-dimensional network that, in the second configuration and depending on the locations chosen to be activated in said first phase, includes different liquid paths having several passage portions situated in offset planes parallel to the plane of the first plate, at least on each side of this first plate, and between which said one or more perforations is situated.
