Nanocapsules: a New Approach in Drug Delivery

Nanocapsule consists of a thin membrane surrounding a core (Liquid, solid) with their size ranging from 10nm to 1000 nm. Nanocapsules are submicroscopic colloidal drug carrier systems composed of an oily or an aqueous core surrounded by a thin polymer membrane. The membrane may be composed of natural or synthetic polymers. Two technologies can be used to obtain such Nanocapsules: the interfacial polymerization of a monomer or the interfacial nano deposition of a preformed polymer. The nanometric size of Nanocapsule can be interesting for many applications like cosmetics, perfumes or pharmaceutical industries. This article is an extended review of these Nanocapsule technologies and their applications for the treatment of various diseases. The Nanocapsule is used in various fields for drug delivery in case of tumors, as a Nanocapsule Bandages to Fight Infection, as a liposomal Nanocapsule in Food Science and Agriculture, in delivering radio therapy and as a self healing material.
