Abstract: A method for fabrication of a chip for surface enhanced Raman spectroscopy (SERS), including: providing a substrate; texturing a surface of the substrate to form a plurality of pillars randomly on the surface until a desired average pillar height, average pillar width and/or pillar density is/are reached; depositing a metal onto the surface of the textured substrate; and thermally annealing the metal such that the metal forms a layer encasing the pillars.
