Polymeric nanoparticles are nano scale drug carrier. It can be modified by various surface modification reactions and the surface properties can be changed by covalent binding as well as adsorption of various agents which mimics ligand for specific receptors of cell. In addition, these ligands are used for target specific drug delivery and for diagnostic purpose, termed as theragnostic agent. According to polymer properties, we can deliver hydrophobic or hydrophilic drug to a specific target. This review focuses on various techniques of targeting the nanoparticles to a specific site, along with this various preparation techniques, patent invention and their future prospects.
