Abstract (en)

[origin: WO2007138178A2] The invention relates to a method for treating drops in a microfluid circuit, comprising at least one microchannel (12) through which the drops flow, characterised in that a laser (26) is brought to bear on the interface of said drops in the transport liquid (F3), or on the interface of drops in contact, in order to carry out a sorting of the drops, to form nanodrops from a larger drop or to fuse drops (60, 64) in contact and initiate reactions between the fluids contained in said drops.
