Abstract:
1. A method of forming a droplet of a second fluid in a first fluid contained in a microfluidic circuit, the method consisting in; bringing the second fluid to an inlet of a chamber containing the first fluid, the inlet of the chamber comprising two opposite walls of the chamber that diverge inside the chamber, urging the second fluid into the inlet of the chamber to form a finger of the second fluid projecting into the chamber and attached to the second fluid, the finger enlarging progressively between the two opposite diverging walls of the chamber, the finger being flattened between said opposite diverging walls, until its upstream end becomes detached from the delivery of the second fluid, to form the droplet, wherein said microfluidic circuit does not comprise any additional channel conveying a flow of said first fluid for shearing the second fluid and forming said droplet.
