SERS signal of selected reporters on GNS. (a) SERS spectra of the 15 selected Raman reporters. (b) Correlation matrix built from the SERS spectra. The color bar indicates the level of overlapping signals, where 1 (yellow) means 100% overlap and 0 (dark blue) means 0% overlap. Name legend: brilliant cresyl blue (BCB), crystal violet (CV), methylene blue (MB), malachite green isocyanate (MG), methylene green (MEG), neutral red (NR), rose bengal (RB), rhodamine 6G (R6G), victoria blue (VB), 4-aminothiophenol (ATP), BPE, MBA, 3,5-dichlorobenzenthiol (DCT), pentachlorothiophenol (PCTP), and 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB).
