Preparation Methods of Liposome and Prospects
AbstractLiposomes made from phospholipid self-aggregation have gradually aroused peoples attention since the early 1970 s, because this kind of drug delivery system can deduce the drug toxity and have the target property. In recent years, major advances spring up in the fields of preparation techniques, preparation material and surface modifiers. This paper describes commonly-used liposome preparation methods and how to evaluate encapsulation efficiency. It also introduces some state-of-the-art technologies, as well as the application in some realms.
