Large‐Area Nanocontact Printing with Metallic Nanostencil Masks

Abstract

There's more behind these masks: Masks composed of Au nanohole-array films on a poly(dimethylsiloxane) (PDMS) slab were used to create high-density molecular patterns. Nanohole films of different thicknesses produced either edge patterns or 1:1 patterns (see examples; scale bars: 2 μm). Hierarchical patterns were created with a single nanostencil mask by using a patterned PDMS slab or by combining nanostencil printing with microcontact printing.
