Abstract

A nucleic acid-encapsulating lipid nanoparticle according to the present invention comprises: a lipid membrane structure having, as constituent components, a lipid bonded to poly(2-methacryloyloxyethyl phosphorylcholine), a cationic lipid, a non-cationic lipid, and a sterol; and a nucleic acid included in the lipid membrane structure. The molar ratio of the cationic lipid in the lipid membrane structure is 20-80%.
