(a) The SERS spectra of ACE with different concentrations in the presence of rGO/AuNP; (b) fitting results of peak intensity (I) and concentration (C) based on different characteristic peaks. (I) Linear regression with the characteristic peak at = 550 cm−1; (II) linear regression with the characteristic peak at = 660 cm−1; (III) linear regression with the characteristic peak at = 798 cm−1; (IV) linear regression with the intensity ratio between = 550 cm−1 and = 1022 cm−1; (V) binary linear regression with the characteristic peak at = 550 cm−1 and = 660 cm−1.
