ABSTRACT

Nanocapsule ranges from 10nm to1000nm. They consist of liquid or solid core in which the drug is placed into cavity, which is surrounded by a natural or synthetic polymer membrane. Nanocapsules are used for the controlled release as well as the drug targeting. The methods used for the preparation of nanocapsules are nanoprecipitation, emulsion co-acervation, emulsion diffusion, polymer coating, layer by layer. The most important characteristics in the preparation of nanocapsules is particle size and size distribution which can be evaluated by different techniques like X-ray diffraction, scanning electron microscopy, transmission electron microscopy and differential scanning calorimetry.
