▎ 摘　　要

NOVELTY - The method involves depositing a graphene layer on a first metal substrate. The multiple metallic nanoislands on the graphene layer. The first metal substrate is removed from the graphene and the deposited metallic nanoislands to form the substrate for surface-enhanced Raman scattering. USE - Method for forming a substrate for surface-enhanced Raman scattering. ADVANTAGE - The ability to predict the morphology and the manipulability of the graphene-supported nanoislands can enable applications in chemical and mechanical sensing. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of performing surface-enhanced Raman scattering of an analyte; and (2) a method for performing surface plasmon resonance of an analyte. DESCRIPTION OF DRAWING(S) - The drawing shows a pictorial view of a simulation box.
