(color online) (a) SERS spectra of CV solution at different concentrations. (b) Logarithmic quantitative relationship curve of the 1618-cm−1 Raman peak intensities of CV; 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).
