Gold-coated glass nanoparticles capable of invading a cancer tumor and destroying it with heat have been developed by Nanospectra Biosciences, a Rice University spinoff in Houston, Texas. The particles measure 150 nm in diameter, which makes them small enough to pass through the leaky blood vessels that characterize cancer tumors.

Therefore, the gold-coated particles should accumulate more in the tumor than in other parts of the body. When near-infrared light is directed at the tumor site, the particles absorb the ...
