Gold nanorods image tumors

By linking gold nanorods to an antibody that binds to tumor cells, researchers have found that gold nanorods will align themselves in an ordered fashion on the surface of cancer cells, further intensifying the optical signal the nanorods produce and providing a unique optical signature for tumor cells.
