Lipid nanoparticles are a drug delivery system that can be used to deliver a wide range of drugs, including anti-cancer agents, antibiotics, and other types of medications. These lipid nanoparticles are made by creating a suspension of lipids in an aqueous solution, and then using a variety of techniques to create a uniform and stable dispersion. The lipid nanoparticles can then deliver a drug payload by either encapsulating the drug or by using the lipid nanoparticles to target a specific area of the body.
