The patterning of single-stranded DNA with a pattern period of 63 nm and a pattern diameter of 40 nm is successfully demonstrated using a gold disk array formed on a highly ordered anodic porous alumina substrate. The formation of DNA patterns is confirmed indirectly by observation of adsorbed streptavidin-coated colloidal Au particles as markers of DNA fixation. Thus, it is demonstrated that nanopatterning of DNA can be achieved using inexpensive equipment and conventional techniques. The present process allows for complete control of the size and periodicity of the Au disk array, which enables the formation of a highly regular arrangement of nanometer-sized patterns of biological molecules.
