| Abstract Scope |
Ionizing radiation such as X-rays offers several therapeutic benefits, including deep tissue penetration and the potential for combined approaches using nanomaterials to improve the outcome. While this is an exciting field, the interaction between X-rays and gamma rays with nanomaterials has not been thoroughly explored; the phenomena of radioluminescence and radiation enhancement are particularly important. Understanding the mechanisms by which luminescent nanoparticles interact with ionizing radiation would allow new imaging and therapeutic modalities to be implemented.
This research investigates the luminescent properties of lanthanide-doped nanocomposites based on phosphates and vanadates under X-ray excitation. Moreover, different nanostructures decorated with gold are evaluated as potential catalyst materials for the production of reactive oxygen species (ROS) under clinical conditions. The dopant concentration was varied to optimize the light yield, and their radiation hardness was evaluated. Additionally, various nanoparticle synthesis routes were explored. |
