Abstract: A microfluidic mixing device (101) comprising: a mixing chamber; one inlet channel (104) into the mixing chamber (102) for a first fluid and two inlet channels (103a, 103b) into the mixing chamber for a second fluid, said inlet channels being disposed substantially symmetrically at a proximal end (108) of the mixing chamber; at least one outlet (105) for mixed material at a distal end of the mixing chamber, wherein the mixing chamber comprises one or more baffles.

Abstract: The present invention relates broadly to microfluidic devices, particularly microfluidic devices optimised for the industrial production of nanoparticles such as liposomes. The device (101) comprises a substrate which extends between a distal end (107) comprising an outlet region (105) and a proximal end (108) comprising an inlet region (106). The inlet region comprises two substantially parallel outer channels (103a, 103b) for transport of a first fluid, said outer channels (103a, 103b) defined in part by a first outer wall (109a) and a second outer wall (109b) respectively, and a linear inner channel (104) for transport of a second fluid. The linear channel is disposed between the two substantially parallel outer channels. The outer channels (103a, 103b) and inner channel (104) extend from the proximal end (108) to a mixing chamber (102) which extends from the inlet region (106) to the outlet region (105).
