AB  - Integration of metamaterials onto a flexible substrate can provide many 
      advantages such as transparency, deformability, light weight and 
      biocompatibility. Here we demonstrate a simple and convenient nickel sacrificial 
      layer-assisted transfer method to fabricate visible-near infrared (IR) 
      metamaterials embedded into a thin polydimethylsiloxane (PDMS) film. Both the 
      structures and the optical properties are maintained after transferring into the 
      PDMS film from a rigid substrate. This PDMS-based metamaterial can behave as a 
      high performance surface enhanced Raman scattering (SERS) device with tunable 
      plasmonic bands, which decouple the preparation of SERS structure and the linkage 
      of targeted molecules to the plasmonic structures. By simply covering the PDMS 
      metamaterials device on the surface with molecules of interest, we demonstrate 
      the application of 2-naphthalenethiol molecules self-assembled on a Au film, 
      highlighting the considerable potential of these PDMS metamaterials as a SERS 
      stamp onto any other substrate. What's more, the PDMS-based nanostructures offer 
      a representative model to investigate the interaction between the plasmonic 
      nanostructure and the substrate consisting of different materials by placing PDMS 
      on the surface of the substrate.
