Abstract
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 w ith an average separation of 260 nm. Furthermore, the pattern of the comple x can be controlled by changing the concentration of the DNA solution. The results suggest that this method is effective in achieving positional contr ol of nanoscale arrangements for a wide range of applications. (C) 2001 Ame rican Institute of Physics.
