Lipid Nanoparticles: Defintion
Skip to main content Accessibility help AI Mode All Images Videos Forums Shopping Short videos More Tools Search Results AI Overview Lipid nanoparticles (LNPs) are microscopic bubbles made of fat molecules that safely pack and carry fragile genetic material—such as mRNA—into human cells. They are famous for their critical role in making COVID-19 mRNA vaccines work. Nature +1 How They Work Protection: Genetic instructions like mRNA break down very quickly if they float freely in the human body. LNPs wrap around this cargo to shield it from being destroyed by natural enzymes. Inside Therapeutics +1 Delivery: Because human cell walls are also made of fat, LNPs easily fuse with or are absorbed by cells, dropping their helpful genetic payload right inside. Single Use Support What They Are Made Of A standard LNP used for RNA delivery mixes four main types of ingredients: Ionizable lipids: These hold a positive electrical charge in acidic settings to bind tightly to the negatively charge
