Figure 6:

Measurements on ThMo with triangular NPs with d=180 nm and minimum interparticle distance a=100 nm realized for different concentrations of Thiram pesticide: (A) phase difference spectra; (B) absolute differential phase |/| associated to resonance peaks; (C) plot of resonant wavelength shift versus different concentrations of Thiram, the red line indicates the fit of the logistic sigmoid function and, in the inset, the chemical structure of the Thiram; (D) SERS spectra of different concentrations of Thiram achieved with a laser wavelength of 785 nm.
