MTG: The numbers of molecules on the graphene area Nads could be calculated to be 5.12 × 105 through UV-vis spectra of MG-CuPc as reported. Therefore, the calculation of the SERS EF can be obtained through the same expression. Considering ISERS = 15,200 and Ibulk = 200, the EF was calculated to be ~1.06 × 106.

For the calculation of Nbulk, to ensure that CuPc molecules on silicon foils contribute to the Raman signal equally, a concentration-dependent experiment was carried out and shown in fig. S9A. A good linear relationship between the concentration of CuPc and the Raman intensity at 1530 cm−1 was observed, ranging from 1 to 12 mM (fig. S9B), indicating the equal contribution of each CuPc molecule on silicon foils to the Raman signal.
