The increasing need for high security level anti-counterfeiting label in order to counteract the money loss coming from fake goods is the source of the present work. Using an already well developed SERS platform this thesis aims to show the possibility of creating a SERS based anti-counterfeiting label for mass production, due to the high nanopillars based SERS device cost efficiency. Different approach have been studied in order to characterize in a unique way each label exploiting molecular spectrum manipulation.
