Nanostructures spun into regenerated silk fibroin fibers encode physical and chemical information. These materials are composed of Raman enhancing nanoscale structures whose location in a linear array and chemical functionality endow them with a tunable identity or code. These structures remain functional after being electrospun into fibroin fibers and report a unique spectroscopic signature to prove the authenticity of a material through their code and by uniquely linking it to the composition of the host material.
