Abstract

Polymeric nanoparticle are of great importance in the treatment of various diseases, due to the flexibility in the modification of their structures. Recent advances in the field of nanotechnology facilitate the engineering of multifunctional polymeric nanoparticles. All the scientific efforts of the pharmaceuticals companies are mainly focusing on two basic aspects, one is to discover new molecules of potential therapeutic interest and second is to develop of a new drug delivery system. In the last few decades, research and development (R&D) scientists has directed their efforts toward formulating novel drug delivery systems that includes sustained and controlled release, modified release and targeted drug release dosage forms. Application of nanoscience and nanotechnology has opened several new possibilities in development of formulation This review compiles the different preparation methods of polymeric nanoparticles and then briefly explained their current potential applications.
