A system for dispensing at least one makeup product, including a cup and a dispenser for filling the cup from the bottom with at least one product, the cup being secured to the dispenser at least while it is being filled with said product. The method for dispensing and evaluating makeup, including the steps of: allowing a video link to be established, for example over the Internet, from a camera at a first site to a second site, allowing the second site to operate either directly or indirectly a dispenser of such a dispensing system, present at the first site, this dispenser making it possible to vary the colour of mixture dispensed, and allowing a person present at the first site to apply the mixture dispensed and to send to the second site a corresponding image, so as to receive in return information relating to the result of the makeup.

Limit size lipid nanoparticles, methods for using the lipid nanoparticles, and methods and systems for making limit size lipid nanoparticles.

The present invention provides microfabricated substrates and methods of conducting reactions within these substrates. The reactions occur in plugs transported in the flow of a carrier-fluid.

Disclosed herein are fluidic mixers having bifurcated fluidic flow through toroidal mixing elements. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (DVBM). The DVBM utilize Dean vortexing and asymmetric bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing. The disclosed DVBM mixers can be incorporated into any fluidic (e.g., microfluidic) device known to those of skill in the art where mixing two or more fluids is desired. The disclosed mixers can be combined with any fluidic elements known to those of skill in the art, including syringes, pumps, inlets, outlets, non-DVBM mixers, heaters, assays, detectors, and the like.

A method includes, under control of control circuitry implementing a mixing protocol, aspirating reagents from multiple different reagent reservoirs into a cache channel. Designated amounts of the reagents are automatically aspirated from the corresponding reagent reservoirs by corresponding sippers based on the mixing protocol implemented by the control circuitry. The method also includes discharging the reagents from the cache channel into a mixing reservoir, and mixing the reagents within the mixing reservoir to form a reagent mixture.

There is disclosed a capillary microfluidic circuit including a main channel communicating with a flow inducing element. The main channel has intermediary inlets. Reservoirs for containing one or more liquids prior to being drawn into the main channel. The reservoirs include a first reservoir and at least a second reservoir. Each of the reservoirs has an upstream end connectable to vents for filling the reservoirs with the one or more liquids and a downstream end. The downstream end of each of the reservoirs is connected to the intermediary inlets of the main channel A conduit is disposed between the first reservoir and the a least a second reservoir. The conduit links the downstream end of the first reservoir with the upstream end of the at least a second reservoir.

A method and a system are described for mixing liquid chemicals at dynamically changing or static ratios during a given dispense, with extremely high uniformity and repeatability. A mixer includes multiple fluid supply lines including elongate bladders defining a linear flow path and being configured to laterally expand to collect a process fluid and laterally contract to deliver a selected volume of the process fluid to the mixer.

A mixer mixes exhaust gas (A) flowing in an exhaust gas-carrying duct of an internal combustion engine with reactant (R) injected into the exhaust gas-carrying duct. The mixer includes a mixer body (26) with a reactant-receiving duct (32) as well as a releasing device (36) with a releasing duct (34). The releasing device adjoins the reactant-receiving duct (32) in a transition area (42) and leads away from the reactant-receiving duct. The releasing device (36) has an asymmetric configuration in relation to a longitudinal axis (LR) of the reactant-receiving duct.

The invention describes a method for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, comprising the steps of: a) compartmentalising the compounds into microcapsules together with the target, such that only a subset of the repertoire is represented in multiple copies in any one microcapsule; and b) identifying the compound which binds to or modulates the activity of the target; wherein at least one step is performed under microfluidic control. The invention enables the screening of large repertoires of molecules which can serve as leads for drug development.

A micromixer and a process of fabricating the same are disclosed which comprises a bottom housing layer having an receiving section, a mixing channel, and an output section; a top housing layer further comprising a plurality of inlet passages, and an outlet passage for obtaining the resulting mixture; the receiving section is coupled to the plurality of inlet passages, and the output section is coupled with the outlet passage; and the mixing channel further comprising a plurality of parallel zigzag channels created by a first zigzag mixing unit and a second zigzag mixing unit.
