Lipid Nanoparticle Surface Engineering with Heparosan Polysaccharides Enhances mRNA Efficacy via Reduced Endosomal Retention
In this study, we developed a library of mRNA lipid nanoparticles (LNPs) containing clinically used ionizable lipids. We surface-modified these nanoparticles with heparosan polysaccharides and systematically compared their performance with conventional poly(ethylene glycol) (PEG)-modified formulations. Our heparosan (H...
