Abstract

The lower part of polymeric nanopillars is made mechanically stiff by surrounding it with metal, while the top part of the pillars is soft. The metal-shell-free tops of the pillars could be used for fabricating hollow structures or decorated with functional materials. This mechanical reinforcement shows stability against capillary-force-induced clustering and enables applications in a water environment.
