Abstract
The present invention discloses a method for fusing or contacting reactor and reagent droplets in a three-phase microfluidic or millifluidic system with one of the phases being continuous, in which the reagent droplet is injected in the droplet train before it coalesces or contacts with the reactor droplet. More specifically, the reagent droplet detaches from the reagent inlet before being in contact with the reactor droplet. The method of the invention involves two successive but not concomitant steps: first producing in the droplet train a droplet of a reagent which breaks-up from the reagent reservoir before the second step of merging. The invention also discloses a milli/microfluidic device whose equivalent circuit is represented on FIG. 11.
