  • Publication number: 20240050908
    Abstract: Provided are scalable, parallelized microfluidic chips that include arrays of microfluidic mixing channels for large-scale production of lipid nanoparticles, among other products. The disclosed chips can operate with a single set of inlets and outlet, and achieve production rates in excess of those achieved by existing methods. The disclosed devices provide large-scale production of formulations while still maintaining the physical properties and potency typical of existing methods of producing such formulations. Also provided are related methods of using the disclosed devices.

  • Publication number: 20230035221
    Abstract: A magnetic separation device has a membrane having a plurality of pores, a magnetically soft material layer disposed on the membrane, and a passivation layer disposed on the magnetically soft material layer. The magnetic separation device may be part of a microfluidic device having a lateral flow channel and a vertical flow magnetic separation filter. The magnetic separation device may be used to separate magnetically tagged particles, such as cells.

  • Publication number: 20220105509
    Abstract: In one embodiment, a microfluidic device has a substrate that defines a first inlet for a continuous phase fluid, a second inlet for a dispersed phase fluid, and droplet generators that can produce micro-droplets from the continuous and dispersed phase fluids. The substrate defines (i) a plurality of delivery channels in fluid communication with the first and second inlets, each delivery channel having a first dimension along a first plane that is perpendicular to a transverse direction, and (ii) a plurality of trenches that extend from the delivery channels towards the droplet generators along the transverse direction. Each trench has a second dimension along a plane that is perpendicular to the transverse direction that is smaller than the first dimension. The substrate defines a plurality of vias that extend from the trenches to the droplet generators so as to fluidly connect the delivery channels with the droplet generators.

  • Patent number: 10799867
    Abstract: Aspects of the present invention relate to apparatuses for microdroplet generation and methods of manufacturing such apparatuses. In accordance with one aspect, a method for manufacturing a microdroplet generator having a plurality of flow-focusing generators includes forming a cavity between a first plate and a second plate, the second plate being a soft master. The cavity defining the plurality of flow focusing generators, a first plurality of channels, and a second plurality of channels. The method further includes supplying a resin to the cavity, applying pressure to one or both of the first plate or the second plate; and curing the resin.
