Substrates with structures at the nanoscale are produced using a method presented by Stefan Kudera and co-workers on page 102. Colloidal nanocrystals are first synthesized in solution and then exposed to a ligand exchange. A monolayer of the particles covered with a thick layer of polystyrene is formed on the substrate. This results in a regular arrangement of the nanoparticles with tuneable interparticle distances. The method is accessible to different shapes and types of nanoparticles.
