In recent years, the fabrication of nanostructured materials and exploration of their properties have attracted the attention of physicists, chemists, biologists, and engineers. Interest in such systems arises from the fact that the mechanical, chemical, electrical, optical, magnetic, electrooptical, and magnetooptical properties of these particles are different from their bulk properties and depend on the particle size. There are numerous areas where nanoparticulate systems are of scientific and technological interest. To produce these systems in appropriate matrices is a significant challenge. This article considers nanoparticles in nanofilms of polyelectrolyte. First, we will briefly review some key areas of applications of nanoparticle systems, with an emphasis on nanoparticles in matrices, and then we will address the area of layer-by-layer deposition of polyelectrolytes. Finally, nucleation and growth of nanoparticles in nanofilms of polyelectrolytes will be discussed.
