Introduction Over the past decade, lipid nanoparticles (LNPs) have emerged as a cornerstone technology in nucleic acid drug delivery , enabling the clinical success of messenger RNA (mRNA), small interfering RNA (siRNA), and gene-editing modalities such as CRISPR-Cas9. Approved products like Onpattro® (patisiran) and the mRNA COVID-19 vaccines from Pfizer-BioNTech and Moderna have demonstrated that effective delivery—rather than payload design alone—is often the decisive fa
