- TITLE SYSTEM FOR PRODUCING A MIXTURE OF FLUIDS IN A MICROFLUIDIC CHANNEL AND ASSOCIATED METHOD IN PARTICULAR FOR THE FORMULATION OF DRUGS BASED ON LIPOSOMES BY THE CHILLED INJECTION OF TWO LIQUID PHASES
- the present invention relates to a system for producing a mixture of fluids in a microfluidic channel and an associated method in particular for the formulation of drugs based on liposomes by the chopped injection of two liquid phases.
- the invention aims to effectively remedy these drawbacks by proposing a system for producing a mixture of fluids comprising:
- microfluidic mixer comprising at least a first inlet port and a second inlet port associated with at least a first valve and a second valve, - the first container being connected to the first inlet port via the first valve and the second container being connected to the second inlet port via the second valve,
- said microfluidic mixer further comprising at least a first microfluidic conduit and a second microfluidic conduit, the first microfluidic inlet conduit being in fluidic communication with the first inlet orifice and the second microfluidic inlet conduit being in fluidic communication with the second inlet orifice, said first microfluidic inlet conduit and said second microfluidic inlet conduit intersecting at a non-zero angle relative to the location of an intersection opening onto at least one outlet channel common, and
- control unit capable of controlling a pressure level of the first fluid inside the first container and a pressure level of the second fluid inside the second container as well as opening and closing of the first valve and of the second valve to carry out successive injections of the first fluid and the second fluid inside the microfluidic mixer, so as to generate a fringe profile of the first fluid and the second fluid inside the common outlet channel.
- the invention thus makes it possible to produce a rapid and homogeneous mixture which is necessary for the formulation of small nanoparticles, in particular less than 100 nm. Due to the absence of a static liquid-liquid interface as well as ultra-rapid pressure variations, the invention drastically reduces the aggregation of nanoparticles and their accumulation in the microfluidic channel. Avoiding clogging of the microfluidic circuit also reduces the formation of fluidic instabilities. Furthermore, the invention makes it possible to reduce the duration of dilution of an organic-lipid phase in an aqueous phase to less than 1 ms thanks to the alternate and optimized generation of organic-lipid and aqueous fringes in a pulsed manner allowing formulation of liposomes with high size monodispersities.

- the first valve and the second valve are solenoid valves with low dead volume, in particular less than 5 pL, and high responsiveness, in particular less than 5 ms.
