Abstract : Polymeric nanoparticles are sub-micron level colloidal particles in the form of nanospheres or nanocapsules. These 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, etc. can be arranged in such a way as to get welldefined nanostructures and can also be used for the modification nanoparticles. These polymeric nanomaterials have wide applications in the field of drug delivery, bioimaging, storage, photocatalysis, biosensing, chemosensing, semiconduction, water purification, composite fabrication, etc. This chapter tries to bring to light the various fabrication and characterization methods of polymeric nanoparticles. Applications of these polymeric nanoparticles are also discussed in detail with special emphasis on spectroscopic investigations.
