SERS spectra taken from nanocubes 38 nm in edge length (top trace) and nanospheres 35 nm in diameter (middle trace) and the normal Raman scattering spectra (bottom trace), for three different molecules: (A) 1,4-benzenedithiol (1,4-BDT), (B) 4-methyl benzenethiol (4-MBT), and (C) 1-pentanethiol (1-PT). The numbers above each spectrum represents the scale in adu mW−1 s−1. In (C), the peak at 1640 cm−1 is from water and is present because of the low Raman intensity of 1-PT on nanospheres.
