Figure 6 Gold nanoshells can destroy cancer cells both in vitro and in vivo. a. Cells incubated with gold nanoshells can be killed by NIR light (dark area). b. Temporal plots of maximum temperature change of NIR-irradiated tumors with and without nanoshells at depths of 2.5 mm and 7.3 mm beneath the tissue surface. c. Gross pathology after in vivo treatment with nanoshells and NIR laser revealed hemorrhaging and loss of tissue birefringence beneath the apical tissue surface. Hematoxylin/eosin (H&E) staining within the same plane confirms tissue damage within the area that contains nanoshells. Copyright © 2008, PNAS.
