▎ 摘　　要

NOVELTY - Method for detecting clenbuterol in animal-based foods based on complex nanomaterials involves (a) preparing secondary deep graphene oxide-supported nano-gold (ro-GO/AuNPs) as a surface-enhanced Raman spectrum (SERS)-enhanced complex substrate, (b) pre-processing the clenbuterol (CL) sample in the animal-derived food to be tested to obtain a test solution, (c) adding the ro-GO/AuNPs complex substrate to the solution to be tested, and performing Raman scanning to collect spectral data in a corresponding range, and (d) for the collected spectral data, taking Raman absorption at Delta v of 1265 cm-1, 1474 cm-1, 1602 cm-1 as a characteristic qualitative peak of clenbuterol, and performing quantitative calculation by Raman absorption intensity at Delta v of 1474 cm-1 to realize the detection of clenbuterol. USE - The method is useful for detecting clenbuterol in animal-based foods. ADVANTAGE - The method detects clenbuterol in animal-based foods rapidly with high sensitivity, good repeatability and improved detection efficiency.
