One of the major components in the success of nanotechnology is the polymeric nanoparticles. These can be produced with high precision and monodispersity in sizes, which can be as small as 20 nm, using a variety of materials through emulsion polymerization techniques. In order to go from such colloidal systems to the macroscopic objects for the final users, a number of processes are involved which often determine the success of the entire procedure. These include coagulation, densification, compatibilization, surface modification, post-polymerization and macroscopic shaping processes. In most of these processes polymerization reactions play a crucial role. A number of examples of practical relevance are discussed in order to highlight the needs for future research in the direction of understanding fundamental phenomena and developing innovative processes. This includes the use of aggregation and breakage of polymer colloids for the production of controlled porous materials in the form of micro-particles or monoliths. The use of controlled free radical polymerization for creating thermo responsive surfaces exhibiting hydrophilic and hydrophobic characteristics. The inclusion of magnetic nanoparticles in polymeric colloids for producing highly ordered nanostructures through magnetic gelation. Or the modification of the surface of the same colloids for highly dispersed nanocomposite with unique optical properties. Finally, the possibility of producing biocompatible and biodegradable nanostructure for medical applications is discussed.
