▎ 摘　　要

NOVELTY - A silver gyrus/graphene/gold film three-dimensional surface-enhanced Raman spectroscopy substrate comprises a graphene-gold structure substrate and silver gyrus nano structure deposited on the graphene-gold nano structure substrate, where the silver gyrus nano structure is a structure similar to gyrus and brain ditch structure of human cerebral cortex consisting of nano-silver structure. USE - Silver gyrus/graphene/gold film three-dimensional surface-enhanced Raman spectroscopy substrate for use in food safety detection (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing silver gyrus/graphene/gold film three-dimensional surface-enhanced Raman spectroscopy substrate.
