Atlanta — Researchers at the Georgia Institute of Technology and the University of California, San Francisco, have found an even more effective and safer way to detect and kill cancer cells.[snip]
"This makes it more practical than the sphere in terms of treating cancer,” said Mostafa El-Sayed. “For laser phototherapy treatment of skin cancer or, for diagnostic biopsies, the spheres are fine, but for phototherapy of cancer deep under the skin, like breast cancer, then one really needs to use the nanorods treatment.”
