The invention relates to a device for transiently contacting at least one unit for capturing biological targets with a body fluid containing them, a method for recovering the captured targets for analysis, and a system for contacting and recovering a capture substrate included in said unit. The invention relates to samples obtained in particular in vivo from body fluids of the human body, e.g. circulating body fluids, said fluids possibly containing, as targets, proteins, oligonucleotides such as RNA or DNA, antibodies, enzymes or cells. A contacting device () according to the invention comprises: &#x2014;a sampling tip () having a contacting end intended to be introduced into a medium containing said fluid, and&#x2014;the or each capturing unit which is bound to said end and which comprises a capture substrate () defining a target capturing surface covered with at least one biocompatible and porous crosslinked polymer layer () designed to retain the or each capture substrate and only to allow biological particles including targets smaller than a limiting size to pass through, in such a way that the or each capture substrate is recoverable after said contacting by dissolution of the or each layer.

A method for dividing an analyte present in a solution and that is fixed on magnetic particles, and devices to be used in the method and systems for implementing the method. The method includes sedimentation of the magnetic particles together with separation into a plurality of residues. One implementation: forms at least a residue of magnetic particles in a first receptacle; and displaces the at least the residues towards a plurality of second receptacles, preferably by relative translation of a magnetic system. The second receptacle is connected to the first receptacle through a fluid channel.

The invention concerns a microfluidic device for the controlled movement of liquid. The controlled-movement device according to the invention comprises a microchannel () filled with a first liquid (F) and a fluid (F) forming a first interface (I) with the first liquid (F), or forming a first interface (I) with the first liquid (F) and a second interface (I) with a second liquid (F) situated downstream of said fluid (F), and means of moving the first liquid (F) by electrowetting. A control system is provided for controlling the movement of the first liquid (F) according to the position of an interface (I, 1) of the fluid (F).

The disclosure relates to a biological analysis device including:

Device for bioassays with integrated detector

A detection head and collimator for a gamma camera. The detection head includes several elementary detectors with semiconductors adjacent to each other to form a detection plane. The collimator is placed in front of the detection plane and includes a number of ducts laid out in a repetition pattern. The shape of the elementary detectors and the repetition pattern are rectangular in the detection plane.
