Abstract

The disclosure provides nanoemulsion compositions and methods of making and using thereof to deliver a bioactive agent such as a nucleic acid to a subject. The nanoemulsion composition comprises a hydrophobic core based on inorganic nanoparticles in a lipid nanoparticle that allows imaging as well as delivering nucleic acids. Methods of using these particles for treatment and vaccination are also provided.
