Figure 3

Raw SERS signal intensity of S10@Ag (A) and AuNP@Ag (B) samples with different amounts of silver coating. Spectra were acquired with a 1 s exposure time at 785 nm (150 mW power at the sample). Because of the low SERS intensity, spectra from AuNP@Ag contain visible background from the plastic vials used during the measurements. The integrated intensity of the DTDC peak around 1580 cm–1 is shown below the spectra for the S10@Ag (C) and AuNP@Ag (D) samples. Error bars are ±1 standard deviation (n = 7).
