Figure 4: In vivo reflectance intensity and spectral red shift of specifically targeted GNRs. (a) Hyperspectral imaging microscopy setup. (b) Ultraviolet-visible spectroscopy (UV-Vis) bright field and dark field images of the cancerous (I-II) and noncancerous (III-IV) tissues. (c) UV-Vis spectroscopy presenting normalized reflectance spectra for the cancerous and noncancerous tissues, demonstrating the reflectance intensity and spectral red shift of the specifically targeted GNRs.
