Tiny Gold Particles Destroy Tumors with Heat

Graduate students at the Massachusetts Institute of Technology have developed tiny gold nanoparticles that can hone in on tumors and kill them when heated with laser-directed light. The rod-shaped gold particles travel through the blood stream and are snared in the small blood vessels in…

Glowing Nanoparticles Guide Doctors to Tiny Tumors

Safer silicon nanoparticles glow, then degrade into harmless by-products. The tiny, newly designed nanoparticles, a thousand times smaller than the human hair, lodge in cancers too small to see, helping doctors see where tumors are or delivering precise doses of chemotherapy. Scientists at the University…

Tiny Nanoparticles Stop Metastasis in Mice

Researchers at the University of California at San Diego targeted tumor blood vessels with chemotherapy carried by microscopic-sized nanoparticles. Although primary tumors were not affected, blood vessels were destroyed, keeping the tumors from spreading throughout the bodies of experimental mice. The technique allows much lower…
