  • Patent number: 11513438
    Abstract: A process for plasmonic-based high resolution color printing is provided. The process includes a) providing a nanostructured substrate surface having a reverse structure geometry comprised of nanopits and nanoposts on a support, and b) forming a conformal continuous metal coating over the nanostructured substrate surface to generate a continuous metal film, the continuous metal film defining nanostructures for the plasmonic-based high resolution color printing, wherein a periodicity of the nanostructures is equal to or less than a diffraction limit of visible light. A nanostructured metal film or metal-film coated support obtained by the process and a method for generating a color image are also provided.
    Type: Grant

  • Patent number: 9909203
    Abstract: A method for fabrication of metal film with nanoapertures is provided. The method includes the steps of providing a nanopatterned template including a plurality of nanostructures, depositing of the metal film onto the nanopatterned template, and thermally induced dewetting of the metal film to define the nanoapertures in the metal film by diffusion and reflow of the metal film.

  • Publication number: 20090092803
    Abstract: The present invention provides articles and methods for affecting the self-assembly of materials. In some cases, the invention provides an approach for facilitating the self-assembly of various materials, including polymeric materials (e.g., block polymers), nanoparticles, other materials capable of self-assembly, and the like, over relatively large surface areas. Some embodiments of the invention provide articles (e.g., substrates) which, when contacted with a material capable of self-assembly, may produce greater control of self-assembly through the bulk of the material.
