Fig. 2. Characterized flow cytometry (FACS) (I) and plasmonic-enhanced Raman spectra (PERS) (II) of reference viable (A), apoptotic (B) and necrotic cells (C). The black lines in the PERS spectra show the averaged spectra from 30 trials of measurements, and the pink colour indicates their standard deviation (n = 30). The red (1), green (4) and blue (8) colour in the PERS spectra indicates the most representative bands in each population.
