Several intriguing nanostructures , such as mushroom‐like nanopillars, vertical nanopillars (see Figure), and nanospheres, are made using capillary lithography and a new, UV‐curable mold consisting of polyurethane functionalized with an acrylate group. An aspect ratio as high as five is achieved for nanopillars 90 nm in diameter.
