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