Transarterial nanoembolization of hepatocellular carcinoma pancreatic metastases in rats using doxorubicin combined with hollow gold nanospheres (HAuNS) and Lipiodol. A: Doxorubicin fluorescence of 2-mm section of the pancreatic tumor. B: Hematoxylin and eosin staining section showing the pancreas and tumor. C: HAuNS accumulated predominately in the tumor but much less in the pancreas in dark-field microscopy. D: Doxorubicin distribution matches well with HAuNS in fluorescence microscopy.
