Precise pH-triggered cleavage of PEG-lipid conjugates drives endosomal escape of siRNA from fusogenic lipid-based nanoparticles.
Lipid-based nanoparticles (LNPs) are leading synthetic delivery systems for the functional delivery of small interfering RNAs (siRNAs) and mRNA vaccines in vivo. However, current state-of-the-art LNPs, although designed with near optimal properties of fusogenicity for target cell entry and release of RNA APIs, possess...
