Surface-Enhanced Raman Spectroscopy for Monitoring Extravirgin Olive Oil Bioactive Components

Figure 2

EVOO Raman signal measured by conventional micro-Raman spectroscopy (black lines) and SERS signal (red lines). In (a) panel, the raw data (SERS signal is reported magnified 20 times with respect to Raman signal) are reported and in (b) panel, the elaborated signals are shown. An acquisition time of 8 s has been used for the Raman signal and 300 s for SERS.
