Liposomes are microscopic spherical vesicles composed of a phospholipid bilayer, which closely resembles the structure of biological cell membranes. This structural similarity grants liposomes exceptional biocompatibility, often leading to them being termed “artificial cells.”

Liposomes serve as efficient carriers for various substances, including drugs. Their ideal characteristics encompass excellent histocompatibility, low toxicity, and the ability to encapsulate and release substances in a controlled manner.
