This work presents the application of microfluidics to manufacture lipid nanoparticles using regulated nanofluidic pulses for scalable manufacturing. Traditional methods of producing lipid vesicles lack the ability to achieve high-throughput and uniformity. Existing studies using pulsed jetting are capable of producing large lipid microparticles. However, the ability to achieve uniform nanoparticles using pulsed jetting has been very limited. A macro-to-microfluidics system was developed to create pulsed jet flows using micronozzles. Using the existing methods, a lipid bilayer is formed using a two-well chip and the micronozzle is placed in-plane with the bilayer. Upon pulsing the system, a jet flow from the micronozzle deforms the lipid bilayer creating a lipid vesicle. The ability to systematically combine multiple devices together allows for a scalable approach to manufacturing lipid particles.
