ABSTRACT
Polymeric nanoparticles are sub-micron level colloidal particles in the form of nanospheres or nanocapsules. The nanoparticles can be formed by either modifying nanoparticles using a polymer or by the sequential arrangement of long polymeric chains in the form of micro or nanostructures. Dendrimers, block copolymers, peptides, arranged in such a way as to get well-defined nanostructures and can also be used for the modification nanoparticles. The arrangement of soap molecules in water to form a micellar structure by the internal interactions of hydrophilic and phobic ends of soap molecules with water is similar to the self-assembly of block copolymers and macromolecules like lipids and dendrimers. Hence the possibility of arrangement block copolymers, dendrimers, lipids in the form of nanostructures can be utilized for spectroscopic applications. The vast array of nanofillers as well as the various sophisticated fabrication techniques might enable the synthesis of novel polymeric nanoparticles in the future so that specific systems could be tailored for the definite application.
