Quantitative and sensitive detection of prohibited fish drugs by surface-enhanced Raman scattering |
(color online) (a) SERS spectra of MG solution at different concentrations. (b) Logarithmic quantitative relationship curve of the 1617-cm−1 Raman peak intensities of MG; the two added points stand for the results corresponding to two real environments: E1 (environment 1: water for life), and E2 (environment 2: water for aquatic product). |
