MICROFLUIDIC CIRCUIT ALLOWING DROPS OF SEVERAL FLUIDS TO BE BROUGHT INTO CONTACT, AND CORRESPONDING MICROFLUIDIC METHOD

摘要

The subject of the present invention is a microfluidic circuit (1) in which are defined microchannels able to contain fluids and comprising at least one device for forming drops of a solution, means (133) for guiding the drops to a storage zone (130) in which one of the drops can be brought into contact with a drop of another solution, the walls of said microchannel portion forming the first drop‑formation device diverging so as to cause drops of said first solution to detach under the effect of the surface tension of said first solution; said first guide means (133) comprise wall portions of said microchannels that diverge so as to cause said drops to move along under the effect of the surface tension of said first solution.
