Size reduction is a fundamental unit operation having important applications in pharmacy. It helps in improving solubility and bioavailability, reducing toxicity, enhancing release and providing better formulation opportunities for drugs. Nanotechnology is the science that deals with the processes that occur at the molecular level and of nano length scale size. Nanotechnology is a multidisciplinary field, the convergence of basic sciences and applied disciplines like biophysics, molecular biology, and bioengineering. In view of post-GATT (General Agreement of Trade and Tariff) scenario pharmaceutical industries are focusing towards their research on nanotechnology because developing new chemical entity (NCE) is very time consuming and expensive affair and most of the drugs will be off patent very soon causing huge revenue loss. Types of pharmaceutical nanosystems include Liposomes, Dendrimers, Carbon nanotubes, Quantum dots, Polymeric Nanoparticles.
