New method for more effective photothermal tumor therapy with infrared light
(PHYSorg.com Nanotechnology)

Nanorods made of bismuth sulfide kill tumor cells with heat when they are irradiated with near-infrared light (NIR). Chinese scientists are now making these weapons more powerful by remodeling the defect state of the nanorod crystal lattice by adding gold nanodots. As reported in the journal Angewandte Chemie, this could be a good basis for more effective photothermal treatment of tumors.
