Abstract:
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 .
