[0003] Nucleic acid-based therapy has attracted attention in recent years because it has great potential to treat diseases by targeting their genetic blueprint in vivo.Nucleic acid-based therapeutic agents can achieve long-term or even curative effects through gene inhibition, addition, replacement, or editing.However, the clinical translation of both nucleic acid drugs and other therapeutic molecules depends on delivery technologies that improve stability, promote internalization, and / or increase target affinity.

[0004] Lipid-based delivery systems, such as but not limited to lipid nanoparticles (LNPs), can provide an approach for stabilizing and delivering nucleic acids and other therapeutic molecules, and there remains a significant need for advances in this technology. Further advances in design characteristics, such as optimal particle size, encapsulation efficiency, robust manufacturing processes, different lipid affinities, and neutral surface charge, can provide efficient lipid-based delivery systems for nucleic acids and other therapeutic molecules.
