Abstract: Gold nanopillars grow in patterns inside a porous anodic alumina template. On selected positions, defined by a gold "seed" pattern, the gold is electroplated into the pores, while a barrier layer underneath the porous template blocks deposition on the rest of the surface. Large-scale arrays of free-standing nanopillar islands are obtained after selective etching of the alumina template.
