Figure 7

SERS spectra of permethrin solutions with different concentrations such as 0.1 ppm, 0.5 ppm, 1 ppm, 1.5 ppm, 2 ppm, 2.5 ppm, 3 ppm, 4 ppm, 5 ppm, 10 ppm and 20 ppm using Ag nano-dendrite SERS optical fibre substrate (a). The dependence of the vibrational band intensity at 998.9 cm−1 on the permethrin concentration (b), and the inset shows fitting of the linear region of the permethrin concentration of 0.1 ppm–5 ppm.
