Caption

Gold nanorods carrying the heat-inducible TRAIL gene are transfected into cancer cells. Cancer cells express TRAIL receptors while normal cells do not. Illumination by a near-infrared laser warms gold nanorods and induces TRAIL expression in transfected cells. TRAIL then kills the surrounding cancer cells.
