Nanostructured thin films by self-assembly of surface modified colloidal particles

The organization of nanoparticles in thin film form is an important element en route to commercially harnessing the exciting application potential of nanoscale matter. Self-assembly of nanoparticles synthesized by the colloidal route on suitable supports is one of the interesting techniques currently being investigated for realizing such structures. This article attempts to cover recent developments in this area with particular emphasis on the methodology developed in this laboratory for the growth of thin films of colloidal nanoparticles. Some other interesting issues related to application of surface-modified colloidal particles will also be addressed.
