| abstract |
The invention relates to a microfluidic device for injecting series of mobile reaction chambers ( 102, 103 ) having non-miscible segmenters ( 101 ) in micro-channels ( 21 to 26 ), comprising:n injection means ( 10 ) for injecting into microreaction channels alternatingly and in parallel liquid to form mobile reaction chambers and liquid for forming the segmenters; means for controlling the progression of one of the two liquids, applied to act on one zone ( 31 ) of each microchannel delimiting an injection volume of said liquid; the control means being able to cause stopping or slowing of the progression of said liquid over the zone of each microchannel by exerting an action based on a physico-chemical property of the liquid and said action not affecting the other liquid. |
