Stabilizing Anionic mRNA Lipid Nanoparticles by Cleavable Crosslinking of Cholesterol.
Lipid nanoparticles (LNPs) are the leading platform for mRNA delivery, with their in vivo performance governed by lipid composition and colloidal stability. While anionic helper lipids can bias LNP expression toward the spleen, weak RNA-lipid interactions during purification often induce nanoparticle rearrangement and...
