液相間で成分を移動させるマイクロ流体システム及び対応する方法、並びに上記成分を抽出するための上記システムの使用

Japanese Patent JP5871795

B2

The invention relates to a microfluidic system including a unit for extracting elements from one liquid phase to at least one other liquid phase, a use of said system for performing said extraction, preferably for gelling polymer capsules coating such elements by cross-linking, and a method for extracting said elements. Said system comprises a substrate in which a network of micro-channels is etched, including a unit (10) for extracting elements (E), including: a depleting micro-channel (11) which carries a first phase (A) to be depleted; at least one enriching channel (12) which carries a second phase (B) to be enriched, said micro-channels meeting at two junctions upstream (Ja) and downstream (Jb) and forming a transfer chamber (13) between said junctions, each junction being such that the micro-channels are axially parallel or form an acute angle on either side of the junction; and a transfer means (14) arranged in the depleting micro-channel for diverting the elements towards the enriching micro-channel. According to the invention, the transfer means includes blocks (14) extending transversely to the axis of the depleting micro-channel, and the extraction unit includes an interface stabilising means (16) arranged downstream from the transfer means between the junctions and including pillars (16) or a surface coating located on an area of the downstream junction facing at least one of the micro-channels.
