摘要

Rapid and simple detections of two kinds of prohibited fish drugs,crystal violet (CV) and malachite green (MG),were accomplished by surface-enhanced Raman scattering (SERS).Based on the optimized Au/cicada wing,the detectable concentration of CV/MG can reach 10-7 M,and the linear logarithmic quantitative relationship curves between logI and logC allows for the determination of the unknown concentration of CV/MG solution.The detection of these two analytes in real environment was also achieved,demonstrating the application potential of SERS in the fast screening of the prohibited fish drugs,which is of great benefit for food safety and environmental monitoring.
