The invention relates to a method for integrating structures in a support, which comprises the steps: The peripheral space has a radial extension length which decreases from the rear face to the front face.

Method for integrating structures in a support and associated device

The invention provides a device for the gravimetric detection of particles in a fluid medium, comprising a flat electromechanical oscillator (), means for supporting the oscillator, means () for actuating said oscillator and, on either side of the plane of the oscillator (), two cavities () enabling the oscillator () to vibrate when it is activated by the actuation means (), characterized in that at least one of the two cavities () forms an integral part of a channel () for the passage of a fluid over at least one of the faces () of the oscillator and in that said actuation means () take the form of at least one electrode () lying in the same plane as that of the electromechanical oscillator and at a defined distance (g) from the oscillator, so as to ensure that the oscillator vibrates in its plane.

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 relates to a device for displacement of at least a small volume of liquid () under the effect of an electrical control, including a substrate () provided with first electrically conducting means (), the device also comprising second electrically conducting means () arranged facing the first electrically conducting means (), the first electrically conducting means and the second electrically conducting means possibly being connected to electrical power supply means to enable the application of electrostatic forces to the small liquid volume (). The second electrically conducting means include at least one conducting wire () arranged parallel to the substrate and at a fixed distance from the substrate to enable displacement of the small volume of liquid () along said conducting wire () under the effect of the applied electrostatic forces.

A miniaturized photoacoustic spectrometer made from a series of stacked substrates. An infrared source is formed in a first substrate. A filter is formed in a second substrate. A micro-trough is machined in a third substrate and a microphone is formed in a fourth substrate. A fifth substrate has a metallic deposit for reflecting light emitted by the infrared source. Resin sealing is provided between the substrates.
