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

Limit size lipid nanoparticles and related methods

The present disclosure is directed towards improved systems and methods for large-scale production of nanoparticles used for delivery of therapeutic material. The apparatus can be used to manufacture a wide array of nanoparticles containing therapeutic material including, but not limited to, lipid nanoparticles and polymer nanoparticles. In certain embodiments, continuous flow operation and parallelization of microfluidic mixers contribute to increased nanoparticle production volume.

Continuous flow microfluidic system

A 'smart' instrument for mixing (), a microfluidic chip (), and a system wherein they are used to prepare formulations is provided. The microfluidic chip comprises microchannels and a programmable data component. The system achieves optimal formulations for RNA, antisense, peptides and small molecules in the hands of even novice users.

Microfluidic mixing devices and systems

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.

Bifurcating mixers and methods of their use and manufacture

The present disclosure is directed towards a disposable microfluidic cartridge configured for use in a system for the small scale production of nanoparticles used in scientific research or therapeutic applications. The system can be used to produce a wide variety of nanoparticles, including but not limited to lipid and polymer nanoparticles, carrying a variety of payloads. The system provides for a simple workflow which in certain embodiments can be used to produce a sterile product.

In general, existing pet doors are unnecessarily complicated and consequently expensive to produce and/or install. The pet door of the present invention overcomes these problems and provides a readily visible indication of whether a pet is inside or outside a house. The pet door disclosed herein includes a pair of simple rectangular frames carrying a flexible flap with a weighted bottom end for overhanging inner and outer ledges on the bottom ends of the frames, inside or outside of the frames depending upon the location of the pet, i.e. a pet moving through the door will push the flap through the frames, the weight returning the flap to a closed position in the frames with the weight against one bottom ledge.
