The present invention is a multiplexed valve for microfluidic devices suitable for establishing the fluidic communication or the cut-off of said fluidic communication between a microfluidic inlet and a plurality of microfluidic outlets, or a plurality of microfluidic inlets and a microfluidic outlet, or a plurality of microfluidic inlets and a plurality of microfluidic outlets. The structure of this multiplexed valve is characterized by a preferably stratified structure formed by a support base, an elastically deformable membrane and a rigid movable part. This rigid movable part allows a set of positions giving rise to the combinations of conditions for the selective opening or closing of the fluidic communications between the inlets and the outlets.

Fabrication method of microfluidic devices consisting of a sheet (1) which is 200 micrometre thick or less and a rigid part (3), both made of thermoplastic polymeric material includes degasification of a polymeric sheet of thermoplastic material (1), an auxiliary rigid part (2), and a polymeric rigid part of thermoplastic material (3). A temporary bonding procedure, of the degassed thermoplastic polymeric sheet (1) to a degassed auxiliary rigid part (2), is conducted producing a sheet-auxiliary part set (4). A permanent bonding procedure bonds the thermoplastic polymeric sheet (1) of the sheet-auxiliary part set (4) obtained in the previous temporary bonding stage, to the thermoplastic polymeric rigid part (3) which was initially degassed. The auxiliary rigid part (2) of the thermoplastic polymeric sheet (1) permanently bonded to the thermoplastic rigid part (3), is detached to produce a final part which is completely polymeric (5).

The present invention is an apparatus for controlling the flow rate in a specific segment in a microfluidic device. This apparatus is formed by a first interrelated product provided in the form of a portable device comprising microfluidic channels and a second interrelated product provided in the form of a control apparatus suitable for receiving the first portable device. The first portable device comprises at least one plate with at least one open microfluidic channel segment configured on the surface of the plate. On this microfluidic channel segment, there is a thermally conductive sheet closing the open microfluidic channel, said thermally conductive sheet comprising a region on the outer surface receiving a thermal sensor. The same microfluidic channel segment comprises a microvalve, either upstream from the thermal sensor or downstream from the thermal sensor, covered by a flexible sheet, which regulates flow in the microfluidic channel segment depending on the pressure exerted on the flexible sheet. The invention allows regulating flow in the microfluidic channel segment by establishing a flow rate according to a setpoint value in the control apparatus with a closed loop regulation between the signal from the thermal sensor and the microvalve.
