Abstract

Novel delivery nanoparticles composes of two-, or three-component lipid compounds. Compositions comprising such lipid compounds, and related methods of their use are disclosed. Nanoparticle compositions include at least one novel modular lipid as well as additional lipids such as ionizable lipids, and phospholipids. Nanoparticle compositions further including biologically active agents, such as siRNA or mRNA, are useful in the delivery of said biologically active agents to subjects in need thereof.
