(A) Schematic depiction of the liposome formation process based on the SHM design, a chaotic advection micromixer for drug-loaded liposomes, and the chamber layout [68]. (B) Microfluidic system schematic (5-input chip mixing junction, Dolomite, Royston, UK), highlighting the mixing junction [85]. (C) Schematic of the lipid nanoparticle-plasmid DNA (LNP-pDNA) complex formulation strategy employing the Y-shape staggered herringbone micromixer (SHM) (NanoAssemblr Benchtop™, Vancouver, BC, CA) [89]. (D) Three-dimensional view of the invasive lipid nanoparticle (iLiNP) device and the size range of LNPs synthesized [90].
