A method of making solid beads is disclosed, said method comprising: (i) providing a microfluidic device comprising a carrier fluid conduit and a functional fluid conduit which meet at a junction region; (ii) providing a laminar flow of a functional fluid comprising a solvent and a solute along the functional fluid conduit and providing a laminar flow of a carrier fluid along the carrier fluid conduit so as to form droplets of functional fluid in a flow of carrier fluid; (iii) cooling the segments of functional fluid in a conduit of the microfluidic device to form cooled (preferably frozen) droplets; and (iv) providing a liquid into intimate admixture with the cooled droplets so as to cause said solvent to exit said cooled droplets, thus forming solid beads. A microfluidic device for use in such a method is also disclosed.

La présente invention concerne un procédé de fabrication de billes solides, ledit procédé comprenant : (i) la fourniture d'un dispositif microfluidique comprenant un conduit de fluide vecteur et un conduit de fluide fonctionnel qui se rencontrent au niveau d'une région de jonction; (ii) la fourniture d'un flux laminaire d'un fluide fonctionnel comprenant un solvant et un soluté le long du conduit de fluide fonctionnel et la fourniture d'un flux laminaire d'un fluide vecteur le long du conduit de fluide vecteur de manière à former des gouttelettes de fluide fonctionnel dans un flux du fluide vecteur; (iii) le refroidissement des segments de fluide fonctionnel dans un conduit du dispositif microfluidique pour former des gouttelettes refroidies (de préférence congelées); et (iv) la fourniture d'un liquide en mélange intime avec les gouttelettes refroidies de manière à faire sortir ledit solvant desdites gouttelettes, formant ainsi des billes solides. La présente invention concerne également un dispositif microfluidique destiné à être utilisé dans un tel procédé.
