▎ 摘　　要

NOVELTY - A surface-enhanced Raman scattering test strip comprises test strip substrate, where the test strip substrate is loaded with gold graphene composite nano material, and the gold graphene composite nano material has a particle size of 60-70 nm. USE - Surface-enhanced Raman scattering test strip. ADVANTAGE - The surface-enhanced Raman scattering test strip has high efficient, better application prospects and anti-jamming performance, and can be prepared in simple, accurate, rapid manner and environment-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a surface-enhanced Raman scattering test strip, which involves preparing a gold graphene composite nano material solution, mixing the gold graphene composite nano material solution with C18-tetraethylene glycol octadecyl ether amine, centrifuging the supernatant, and resuspending to obtain a positively charged solution of the gold graphene composite nanomaterial in the solution, taking the test strip substrate, and immersing the test strip substrate in the solution to obtain the finished product.
