▎ 摘　　要

NOVELTY - The structure has a carrier i.e. silicon chip, orderly formed with a flower-shaped silver particle layer, a graphene oxide particle layer and a gold nano-micin particle layer. USE - Flower-shaped silver-graphite oxide-gold nano-micin SERS active substrate sandwich structure. ADVANTAGE - The structure has better plasma coupling resonance effect, aesthetic appearance and better surface enhanced Raman scattering effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a flower-shaped silver-graphite oxide-gold nano-micin SERS active substrate sandwich structure preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a flower-shaped silver-graphite oxide-gold nano-micin SERS active substrate sandwich structure.
