Summary: | The invention discloses a CuO@Ag bowl-shaped array and application thereof in cyclic SERS (Surface Enhanced Raman Scattering) detection of aflatoxin. The CuO@Ag bowl-shaped array is obtained by forming a CuO bowl-shaped array on the surface of a copper foil by adopting a gas-liquid interface self-assembly technology and a confinement growth method and then sputtering a layer of Ag nano-particle film. The CuO@Ag bowl-shaped array serving as an SERS substrate has an excellent SERS Raman enhancement effect, excellent stability and sensitivity, can degrade target molecules under visible light, and shows excellent self-cleaning performance and excellent recyclable SERS detection performance. In addition, the CuO@Ag bowl-shaped array has the advantages of being simple in preparation process, low in cost, high in repeatability and the like. Therefore, the CuO@Ag bowl-shaped array can be used for SERS sensing as an SERS substrate.
