Radiosensitizing effect of zinc oxide and silica nanocomposites on cancer cells

- Biocompatible ZnO-silica nanoparticles scintillate in response to ionizing radiation.
- ZnO nanoparticles harvest radiation energy for its conversion to biomedical applications.
- ZnO-silica core-shell nanoparticles offer enhancement of radiation therapy.
- Radiosensitization occurs due to radiocatalysis induced by X-rays at the nanoparticle surface.
