Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue
...the Rice team injected the tumors with gold-coated nanoshells
and exposed the animals to near-infrared light for several minutes. The tumors disappeared within 10 days without damaging any healthy tissue. Future applications Dai points out that the carbon nanotubes also can be delivered to diseased cells by d...
