| Abstract: |
In this study, the effect of γ-radiation from typical commercial medical sources based on X-ray tubes and linear accelerators on the electrostatic properties of radiosensitizing gold nanoparticles located in a tissue-like medium has been evaluated numerically using a Monte Carlo simulation in the Geant4 software package. It has been shown that for realistic radiation doses, a significant fraction of gold nanoparticles of up to ~10‒1 can, at least temporarily, change their surface charge sufficiently to convert anionic gold nanoparticles into cationic ones, which can lead to cytotoxic effects.
