Figure 6: Tricarbocyanine derivatives as Raman reporters: (A) Comparative SERS intensities of the entire CyNAMLA library, with intensity of DTTC, as reference, plotted in red. All the SERS spectra were acquired with excitation at 785 nm using a 60 mW laser. (B) SERS intensities of the six selected aromatic amine containing BSA-encapsulated CyNAMLA coated GNPs, and organic structures of DTTC and CyNAMLA-381 [30].
