Nanotechnology turns up heat on prostate tumors

January 1, 2008

Bathe a prostate tumor in metallic particles that preferentially move through permeable capillaries and into the tumor bed. Shine an infrared light on the particles. The metal, but not the tissue, absorbs infrared energy; as it heats, it destroys tumor cells. Tissue not in contact with the metal particles, ie, healthy tissue, is unaffected.
