Περίληψη :	The research investigates the intricate interactions between lipid-based agents and single-stranded mRNA fragments through the lens of molecular dynamics simulations. By scrutinizing the structural and energetic aspects of lipid-based RNA nanoassemblies, two distinct groups of complexation agents were examined: cationic ionizable agents and electrically neutral amphoteric phosphatidylcholine lipids. The study revealed that the overall charge of the complexation agents significantly influences the energetics of lipid/RNA association, while their degree of hydrophobicity impacts self-assembly and complexation kinetics. Furthermore, these attributes affect the structural stability of the complexes, with water content within less hydrophobic agents affecting the coherence of lipid-RNA nanoassemblies. The interplay of these attributes also dictates the resulting RNA conformation post-complexation. This study offers new insights for fine-tuning the morphology, energetic stability, and structural integrity of lipid-based RNA complexes, with potential implications for the development of advanced biomaterials.
