Liposomes are microscopic, spherical-shaped vesicles composed of a phospholipid bilayer. They can be used as a delivery system for various substances such as drugs, enzymes, and genetic material. Liposomes can be engineered to encapsulate different types of molecules, depending on the desired therapeutic or diagnostic application.
Liposomes are similar in structure to cell membranes, which allows them to fuse with cells and deliver their contents directly into the cell. This property makes them an attractive option for drug delivery systems, as they can potentially improve the efficiency and specificity of drug delivery while reducing toxicity.
Liposomes can be made using a variety of techniques, including sonication, extrusion, and reverse-phase evaporation. The size, shape, and composition of liposomes can be controlled by adjusting the manufacturing process.
Overall, liposomes are a versatile and promising tool for drug delivery and other biomedical applications.
