Gold (Au) nanoparticles have been used for various applications in nanoscience and nanotechnology. A simple and versatile method to prepare the porous structure characterized by lattice constants of a few tens of nanometers, such as Gold (Au), is based on self assembly of diblock copolymers (BCP) and the positions of the holes etched into the substrates were determined by position of pores in the BCM template. On the patterned Si, the ordered arrangement of the gold nanoparticle located inside the pores was unaltered, whereas the gold onto the residual polymer film coalesced and formed large cluster. It can also be immobilized on Si at high temperatures within ordered dense arrays of nanopores prepared by using BCP templates.
