The coupling of ZnO-based nanomaterials with organic photosensitizers (PS) is potentially interesting for cancer treatment under X-ray. In these conditions, ZnO nanoparticles (NPs) convert the X-ray into UV-Vis emission, promoting PS excitation and producing reactive oxygen species (ROS). Main advantages in vivo applications are photostability biocompatibility, even if its efficient different (typically porphyrin) still a controversial issue, as both high luminescence yield good overlapping...
