| The development of nanoparticles drug delivery system is widely expected to change the traditional pharmaceutical system through increased surface specific reactivity and bioavailability. There has been an important research interest in the area of drug delivery systems using nanoparticles. These particles have unique physicochemical properties such as ultra small and controllable size, large surface area to mass ratio and functionalizable structure. They have been used in vivo to protect the drug entity in the systemic circulation, control access of the drug to the chosen sites and to deliver the drug at a controlled and sustained rate to the site of action. Various nanostructures have been used in the drug delivery research to increase therapeutic advantage. Present review discuss about the aspects of the characterization and applications of various nanostructures in drug delivery system. |
