Additional studies are essential in order to understand the underlying processes of radiosensitization so as to use GNPs as a clinical therapeutic tool. In particular, the full mechanisms mechanism  underlying radiosensitization in radiotherapy still need to be investigated in a patient-like geometry. Of note, the efficacy of a treatment depends on the nanoparticles concentration and spatial distribution in the tumor cells, as well as on incident beam energy and delivered dose.When metallic nanoparticles are localized in the tumor a greater fraction of the incident photon energy can be imparted to it without escalating the damage to the surrounding healthy tissues.
