Abstract: Disclosed is a carboxylic acid-functionalized 3-dimensional SERS substrate. A carboxylic acid-functionalized 3-dimensional SERS substrate according to an embodiment of the present invention includes a substrate; a 3-dimensional nanostructure including a multistacked metal nanowire array formed by alternately and repeatedly transfer printing a single-layer metal nanowire array, laminated on a polymer mold on which a pattern of a master mold is duplicated, onto the substrate 110 to be perpendicular to each other; and a functionalized carboxylic acid into which a residue of the polymer mold present on the 3-dimensional nanostructure is functionalized and which enables a target analyte to immobilize.

Abstract: The present invention relates to a surface-enhanced Raman scattering substrate and a method of fabricating the same. More particularly, the surface-enhanced Raman scattering substrate according to an embodiment includes a substrate; a lower plasmonic layer formed on the substrate and based on a first metal nanostructure; an oxide layer formed on the lower plasmonic layer; and an upper plasmonic layer formed on the oxide layer and based on a second metal nanostructure.
