Abstract

Flexible multi-resonant plasmonic sheets, flexible microporous multi-resonant meshes, and dissolvable template-based hierarchical imprinting fabrication methods are described. A method of manufacture of a flexible microporous multi-resonant plasmonics mesh (MMPM) is described in one example. The method includes depositing alternating metal and insulating layers on a solvent-soluble nanowell array, to form a nanolaminate plasmonic crystal (NLPC) array on the solvent-soluble nanowell array. The method also includes pressing a hydrophobic curable resist over the NLPC array and the solvent-soluble nanowell array, using a watersoluble micropillar array as a working stamp for the pressing, curing the hydrophobic curable resist into a flexible scaffold, and dissolving the water-soluble micropillar array in water. The dissolving exposes a first side of the flexible scaffold, with the solvent-soluble nanowell array supporting a second side of the flexible scaffold. The method also includes dissolving the solvent-soluble nanowell array in a solvent, and separating the solvent-soluble nanowell array from the NLPC array and the flexible scaffold.
