Hollow Bi 2 Se 3 nanoparticles prepared by a cation exchange method are loaded with perfluorocarbon as an oxygen carrier. With those nanoparticles, a new concept is proposed by Z. Liu and co‐workers on page 2716 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.
