Gold nanoparticles have been assembled into two-dimensional complexes using a DNA network template. Atomic force microscope images indicate that gold nanoparticles can be artificially arranged using a DNA molecular template with an average separation of 260 nm. Furthermore, the pattern of the complex can be controlled by changing the concentration of the DNA solution. The results suggest that this method is effective in achieving positional control of nanoscale arrangements for a wide range of applications. © 2001 American Institute of Physics.
