Abstract
Novel ionizable lipids, compositions, and methods of using the novel ionizable lipids and compositions are disclosed. Lipid nanoparticle compositions include a novel ionizable lipid as well as additional lipids such as phospholipids, structural lipids, and PEG lipids. Lipid nanoparticle compositions further including biologically active agents such as mRNA or DNA are useful in the delivery of biologically active agents to mammalian cells or organs.
