A liposome is a tiny bubble (vesicle), made out of the same material as a cell membrane. Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases. Membranes are usually made of phospholipids, which are molecules that have a head group and a tail group.

What are liposomes in biology?

Liposomes are small artificial vesicles of spherical shape that can be created from cholesterol and natural non-toxic phospholipids. Due to their size and hydrophobic and hydrophilic character(besides biocompatibility), liposomes are promising systems for drug delivery.

Is liposome a nanoparticle?

Liposomes and lipid nanoparticles are similar in design, but slightly different in composition and function. ... Lipid nanoparticles are liposome-like structure, which is especially suitable for encapsulating various nucleic acids (RNA and DNA). Therefore, they are the most popular non-viral gene delivery system.
