Protection and sensitization of normal and tumor cells to proton radiation by cerium oxide nanoparticles

Abstract

Cerium oxide nanoparticles are investigated as radioprotectors and radiosensitizers for normal (healthy) and tumor cells for charged particle radiation. Results are presented for cell survival and DNA damage for in-vitro irradiation of normal breast epithelial cells and prostate tumor cells by 1.5 - 3.0 MeV protons
