A liposome is a tiny bubble (vesicle), made out of the same material as a cell membrane. Membranes are usually made of phospholipids, which are molecules that have a head group and a tail group. The head is attracted to water, and the tail, which is made of a long hydrocarbon chain, is repelled by water. Since then, liposomes have made their way to the market. Today, numerous lab scale but only a few large-scale techniques are available. Today, they are a very useful reproduction, reagent, and tool in various scientific disciplines, including mathematics and theoretical physics, biophysics, chemistry, colloid science, biochemistry, and biology. Liposomes with modified surfaces have also been developed using several molecules, such as glycolipids or sialic acid. Liposomes are used as model for artificial cells. Liposomes can also be designed to deliver drugs in other ways. The use of liposomes for transformation or transfection of DNA into a host of cell is known as lipofection. Liposome are widely used as carriers of active ingredients to human tissue and as lipid transfer vesicles to the skin. Liposomes find applications in pharmaceutical, cosmetic and other industrial field.
