Figure 10. Photostability comparsion between ICG and SERS NPs in ex vivo liver tissue.

Figure 10

With continuous illumination, the 785 nm laser bleached the ICG fluorescence signal from an ex vivo liver sample, within minutes for all tested intensities, whereas the SERS signal, measured as the intensity of a specific peak (1215 cm−1), remained stable.
