A microreactor is shown having an inlet or feed channel, an inlet or feed zone for a flow of fluid, a reaction zone, an outlet zone and an outlet or evacuation channel, the zones and channels being in fluid communication, and at least one compound such as an enzyme capable of producing a biological or biochemical reaction with at least one constituent of the flow of fluid, the compound being attached to the surfaces of the inlet zone, reaction zone, and outlet zone.

Microreactor, process for the preparation thereof, and process for carrying out a biochemical or biological reaction

The invention concerns a component for biological or biochemical analysis microsystems formed from a support and having at least one chemically functionalised surface zone, in order to allow in said zone the formation of a chemistry for anchoring biological or biochemical elements, and/or electrically, in order to allow in said zone the formation of electrical charges. The support comprises at least one part () formed of a composite material, said composite material being a mixture of at least one inert material and at least one chemically and/or electrically functionalisable material to provide said functionalised surface zone.

Composite material for biological or biochemical analysis microfluidic system

A device measures the propagation time for an acoustic wave in a continuous phase of a two-phase mix ( ) comprising the continuous phase and a dispersed phase forming droplets ( ) in the continuous phase. The device comprises an electro-acoustic transducer ( ) capable of emitting acoustic waves ( ) and outputting a reception signal of reflected acoustic waves, a signal pulse generator capable of determining a propagation time starting from signals output by the transducer, and an acoustic lens for focusing acoustic waves and the frequency of the acoustic waves being adjusted to cause reflection of the waves on the droplets of the dispersed phase, essentially located within a focusing area.

Device and method for determination of physical parameters for a two-phase mix by propagation of an acoustic wave in the continuous phase of the two-phase mix
