Perumalla Jagadeesh*, S.Dasthagiri, G. Nethravani
ABSTRACT
Nanotechnology is the science of small. Nano derives from the Greek word “Nano” which means dwarf small. 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.
Keywords: Natural polymers, Synthetic polymers, Super critical fluid technology, Salting out, Dialysis method.
