ABSTRACT
Nano capsules are vesicular systems in which the drug is confined to a cavity consisting of an inner liquid core surrounded by a polymeric membrane. Nano capsules having various advantages and disadvantages. Preparation of Nano capsules can be used as a two types of polymers 1) Natural polymers 2) Synthetic polymers. Nano capsules are prepared by different method those are a) Solvent evaporation b) Nano precipitation c) emulsification / Solvent diffusion d) Salting out e) Dialysis f) Super critical fluid technology. Different characterization and evaluation tests are performed to Nano capsules. Dispersed polymer nanocapsules can be used as nano-sized drug carriers to get controlled release as well as efficient drug targeting. Drug-loaded polymeric nanocapsules have showed possible applications in the field of drug delivery systems. Enormous research efforts have been performed in order to develop modern nano-particulate drug delivery systems. However, newly developed drug molecules with moderate biopharmaceutical profile are still missing. The entrapment of this drug molecule can protect them from the biological environment and facilitate their transport through biological barriers. Therefore nano-carriers especially nanocapsules (NC) can give the promise for therapeutic benefits in the field of drug delivery system. Nanocapsules, existing in miniscule size, range from 10 nm to 1000 nm. They consist of a liquid/solid core in which the drug is placed into a cavity, which is surrounded by a distinctive polymer membrane made up of natural or synthetic polymers. They have attracted great interest, because of the protective coating, which are usually pyrophoric and easily oxidized and delay the release of active ingredients.
