SERS spectra of SAM solution in different concentration (a). Plot for the comparison of the measured value with the calculated value (b). Each sample was measured for 5 times and the average was calculated. The SAM solution of 0 g/L was used to prove that the peak centered at ~2920 cm⁻¹ was produced by SAM.
