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 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.

主权项

1. A microfluidic circuit, in which are defined microchannels containing fluids, said circuit comprising at least:
one first device for forming drops of a first solution in a carrier fluid, comprising a microchannel portion passed through by said first solution; first means for guiding said drops to a storage area in which one of said drops may be brought into contact with a drop of a second solution,wherein the walls said microchannel portion of said first drop forming device diverge so as to detach drops of said first solution under the effect of the surface tension of said first solution;
and said first guiding means comprise portions of wall of said microchannels, diverging so as to displace said drops under the effect of the surface tension of said first solution.
