An exemplary compounding system and method can include a transfer set that includes a manifold for assisting in transferring a plurality of ingredients from supply container(s) to a final container. The manifold can include a first channel in fluid communication with at least one primary ingredient, and a second channel in fluid communication with a plurality of secondary ingredients. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold. The transfer set can include a plurality of inlet lines in fluid communication with the manifold and two outlet lines configured for connection to two separate pumps and eventually being in fluid communication with the final container.

An embodiment for a microfluidic device is provided. The device comprises two areas, arranged side-by-side, and a trigger channel. They include a first area, which is delimited by a first liquid pinning barrier, and a second area, which is delimited by a second liquid pinning barrier. The latter extends parallel to the first liquid pinning barrier to delimit a corridor. The trigger channel extends through the corridor between the two areas. In addition, the trigger channel connects the first liquid pinning barrier with the second liquid pinning barrier, allowing a first liquid pinned at the first liquid pinning barrier and a second liquid pinned at the second liquid pinning barrier to be contacted, each, by a reverse flow of the second liquid in the trigger channel and thereby start mixing at a level of the corridor, in operation. The invention is further directed to related methods of operation.

A spatially selective surface functionalization device configured to generate a pattern of micro plasmas and functionalize a substrate surface may include: a pattern management system, a patterning head, and a gas delivery system, wherein the gas delivery system provides a primed gas mixture for forming a plasma between the patterning head and a target substrate below the patterning head.

A pattern management system may store and manipulate information about a pattern of surface functionalization and generate instructions for regulating a distribution of micro plasmas that functionalize a substrate surface.

The present invention provides methods and devices for simple, low power, automated processing of biological samples through multiple sample preparation and assay steps. The methods and devices described facilitate the point-of-care implementation of complex diagnostic assays in equipment-free, non-laboratory settings.

An apparatus for mass producing monodisperse microbubbles contains a microfluidic flow focusing device. The microfluidic flow focusing device includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.

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). The mixing chamber (102) is in flow communication with the inner and outer channels (103a, 103b, 104) to receive the first and second fluids from the inner and outer channels (103a, 103b, 104) and the mixing chamber (102) has a uniform width (W) along its length substantially equal to the width (W1) between the outer walls (109a, 109b) of the two substantially parallel outer channels (103a, 103b).

An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material. The method of use also includes connection of a transfer set to a housing in a manner that further ensures optimum efficiency and safety.
