A liposome is an artificially-prepared spherical vesicle composed of a lamellar phase lipid bilayer. The liposome can be used as a vehicle for administration of nutrients and pharmaceutical drugs. Liposomes can be prepared by disrupting biological membranes (such as by sonication).

Liposomes are often composed of phosphatidycholine-enriched phosphalipids and may also contain mixed lipid chains with surfactant roperties such as egg phosphatidylethanolamine. A liposome design may employ surface ligands for attaching to unhealthy tissue.

The major types of liposomes are the multilamellar vesicle (MLV), the small unilamellar liposome vesicle (SUV), the large unilamellar vesicle (LUV), and the cochleate vesicle.

A microcapsule is a small sphere with a uniform wall around it. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Some materials like lipids and polymers, such as alginate, may be used as a mixture to trap the material of interest inside.  Most microcapsules have pores with diameters between a few micrometers and a few millimeters. The coating materials generally used for coating are:

• Ethyl cellulose

• Polyvinyl alcohol

• Gelatin

• Sodium alginate
