Gold "Thermal Scalpel" Targets Cancer

Gold nanoparticles have the ability to turn near-infrared laser light into intense heat. Scientists are looking into how this “thermal scalpel” might be used to kill tumor cells. UAB gene-delivery specialists David T. Curiel, M.D., Maaike Everts, Ph.D., and colleagues reported in the journal Nano Letters (April 2006) that they successfully piggybacked as many as 1,000 gold nanoparticles onto an adenovirus capable of zooming in on tumor cells.
