According to the experts, the photothermal therapy is an attractive therapy technique using photosensitizers to generate heat from light absorption and then kill the cancer cells. To avoid the nonspecific heating of healthy cells and allow deeper penetration into tissues, near-infrared light is usually utilized. Furthermore, because the use of plasmonic nanomaterials as photosensitizers makes this technique possess spatial selectivity, a lot of plasmonic nanomaterials with near-infrared photothermal conversion property have been examined. There are gold nanorods, gold nanoshells, gold nanocages, single-walled or multi-walled carbon nanotubes, graphene or reduced graphene oxide, and germanium. Among them, gold-based nanomaterials received the most attention. However, gold is an expensive noble metal, and the preparation of its nanostructures usually needs an accurate synthesis condition or repeated deposition. Thus, the alternatives with lower cost or simpler preparation method are still in demand. And cesium tungsten oxide is found to meet these requirements.
