摘要
目的采用纸基-表面增强拉曼光谱法(SERS)对染色南五味子进行快速鉴别。方法选用浸泡法制备的银胶纸作为SERS基底,擦拭经乙醇-水溶液润湿的南五味子,银胶纸立即进行SERS检测;先后对银溶胶的浓缩倍数、银胶纸的SERS增强效果及稳定性等因素进行考察。结果成功鉴别低浓度酸性红、赤藓红染色的南五味子。结论纸基-SERS法可实现非法染色南五味子的快速、准确、无损的鉴别,有望应用于快检领域。
Objective To establish a paper-based surface-enhanced Raman scattering （SERS） method for the detection of dyed K adsura longipedunculata Finet et Gagnep .Methods Supported silver nanoparticles on filter paper were synthesized simply by soaking method .In addition ,factors including enrichment ratio of silver nanoparticles ,the enhancement effect and sta-bility of the SERS device were investigated .Results The K adsura longipedunculata Finet et Gagnep ,dyed by Erythrosine or Acid Red at low concentration had been detected successfully .Conclusion Combined with the paper device and SERS ,the ap-proach was rapid and non-destructive which could be used to identification of dyed K adsura longipedunculata Finet et Gagnep .
