Ideally ordered DNA nanopatterns have been formed by selectively opening holes in a barrier layer covering gold‐filled anodic porous alumina, and then adsorbing thiolated DNA onto the exposed gold nanodisks. Fluorescence microscopy of fluorescent‐dye‐labeled thiolated DNA fixed on the gold‐disk array confirms the selectivity of the process (see Figure).
