Perfluorocarbon‐Loaded Hollow Bi 2 Se 3 Nanoparticles for Timely Supply of Oxygen under Near‐Infrared Light to Enhance the Radiotherapy of Cancer

Hollow Bi2Se3 nanoparticles prepared by a cation exchange method are loaded with perfluorocarbon as an oxygen carrier. With these nanoparticles, a promising concept is demonstrated to enhance radiotherapy by not only using their X-ray-absorbing ability to locally concentrate radiation energy in the tumor, but also employing near-infrared light to trigger burst release of oxygen from the nanoparticles to overcome hypoxia-associated radio-resistance.
