▎ 摘　　要

NOVELTY - Surface-enhanced Raman spectroscopy (SERS) substrate, is claimed. The SERS substrate is electrochemically deposited on the AAO film to form a graphene-gold/silver composite. USE - Surface-enhanced Raman spectroscopy substrate for use in electrochemical technical field, chemical, environment, biological and human diseases. ADVANTAGE - The SERS substrate has low cost, high repeatability, no pollution and simple operation, and can be directly used without repreparation, and has uniform size, large area, and good SERS effect. The distribution of the metal nano-particles prepared by the method is uniform, and the size of the graphene-gold/silver nano-composite SERS substrates can be made uniform. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the SERS substrate.
