Abstract

A facile methodology to control the orientation of assembled Au nanorods with a preferential direction on unstructured substrates has been demonstrated by the assistance of an elastomer grating stamp. Quite surprisingly, by choosing the hydrophobicity of the substrate, the aligned orientation can be manipulated to be perpendicular or parallel to the grating direction.
