Ionizable lipid review

WebIn this review, we summarized the current research strategies to enhance stability of the RNA vaccine delivery system. Keywords: COVID-19, mRNA vaccine, SARS-CoV-2, stability, storage 1. Introduction Coronavirus disease 2024 (COVID-19) was first identified in December 2024 in Wuhan, China. WebFirst, ionizable lipid structures were prepared by Michael addition chemistry. Then, the ionizable lipids, PEG-lipid, DOPE phospholipid, and cholesterol were combined into an ethanol phase, and luciferase mRNA was diluted into an aqueous phase. Both phases were mixed at controlled flow rates in microfluidic devices.
