Lasers and Gold Nanoshells Team Up Against Cancer
Tiny gold nanoshells—known for their surface plasmonic properties—may someday help guide cancer-seeking heat therapy to its target.

Bottom left: Scanning electron micrograph shows how the nanoshells are deposited close to the tumor microvasculature. Right: Magnetic resonance temperature imaging of the tumors during irradiation with an 808-nm laser at low power (4 W/cm2) demonstrates a striking difference in heating between the control and nanoshell-treated animals.
