The sampling device (30) and microfluidic network device (13) are formed on a common microfluidic support (12) as a single part.
Fluidic device for aliquoting and combinatorial mixing of liquids
The present invention relates to fluidic devices, especially microfluidic devices, for aliquoting and pairwise combinatorial mixing of a first set of liquids with a second set of liquids. The device architecture is designed to move liquids in two separate phases, a first phase where the liquids are exposed to a first directional force field to move the liquids in a first direction, from a reservoir to aliquot chambers, and a second phase where the liquids are exposed to a second directional force field to move the liquids in a second direction, from the aliquot chambers to the mixing chambers. The first and second directional force fields that the device is exposed to may be achieved using a single directional force field (i.e. a rotor driven centrifugal force field) and by re-orienting the position of the device with respect to the centrifugal forces between the first and second phases of operation. The device architecture comprises reservoirs for each of the first fluids and reservoirs for each of the second fluids. Each reservoir is fluidically connected to aliquoting chambers, either arranged in parallel or in series, for providing aliquots of the fluid which may be metered. The conduits providing fluid communication between the reservoirs and aliquoting chambers are arranged in a first direction. A series of mixing chambers is also provided, and each mixing chamber is fluidically connected to one aliquot chamber for a first liquid and one aliquoting chamber for a second liquid. The conduits providing fluid communication between the aliquoting chambers and mixing chambers are arranged in a second direction.

The second microfluidic module has a second module body including a microfluidic channel, a second connector including a guider configured to guide the protrusion upon insertion of the first connector into the second module body, and a locker configured to fix the protrusion. Upon fluidly coupling the first microfluidic module and the second microfluidic module, an O-ring is disposed between the first connector and the second connector.

CARTRIDGE FOR USE IN A SYSTEM FOR DELIVERY OF A PAYLOAD INTO A CELL
A cartridge for delivering a payload to cells of a cell suspension is provided, wherein the cartridge comprises an input channel that delivers the cell suspension to a first plurality of branch channels, and wherein the first plurality of branch channels each deliver the cell suspension into a respective one or a plurality of microfluidic chips or filters. Cell suspension exiting a microfluidic chip or filter flows into a respective one of a second plurality of branch channels, and is then delivered to an output channel by which it exits the cartridge. The cartridge may comprise a plurality of removable covers that hold the chips or filters in place against a body of the cartridge in which the input channel, output channel, and branch channels are formed.
BIOSENSOR SYSTEM FOR MULTIPLEXED DETECTION OF BIOMARKERS
The invention refers to a biosensor system for quick and multiplexed detection of biomarkers present in biological fluids. The biosensor system comprises a reusable array of at least two individual electrochemical cells (1a,1b,1c,1d,1e) coupled to a disposable fluidic component. Each cell can be addressed individually. The array includes a set of working electrodes (2a,2b,2c,2d) and at least one shared counter/reference electrode (5) in common for all the electrochemical cells, such that each electrochemical cell includes one working electrode and the shared counter/reference electrode. Preferably, the system includes a disposable paper component (8) having a reactive microfluidic component distributed in fluidic channels (9), isolated by hydrophobic barriers (10). The paper component (8) is operatively aligned with the array of electrochemical cells for the electrochemical detection by means of a polymeric cartridge. The multiplexed biosensor system features a reduced size, and that allows reduction of analysis costs and material waste.
