In recent years, our group is studying on the seed-mediated growth method as a new strategy to attach and grow metal nanoparticles on conducting substrates, such as indium tin oxide (ITO). In this method, metal nanoparticles can be fixed via simple two-step immersion of a substrate into two different solutions at room temperature. The first step includes the physi-sorption of seed-nanoparticles on the substrate surface in the metal colloid solution (seed solution), and the second step is the gradual nanocrystal growth from the seed particles attached on the substrate by the chemical reduction of metal ions in the solution containing surfactants (growth solution). In this paper, some details of our approach and successful applications obtained up to now are described.
