One of the most attractive areas of research in drug delivery today is the design of nanosystems that are able to deliver drugs at right place, at appropriate time in right dosage. These nanocarriers are sub micron particles containing entrapped drugs intended for enteral or parenteral administration which might prevent or minimize the drug degradation and metabolism as well as cellular efflux. Nanoparticles also have a long shelf life, are made of safe materials, including synthetic biodegradable polymers, natural biopolymers, lipids and polysaccharides and have the potential for overcoming important mucosal barriers, such as intestinal, nasal and ocular barriers.
