Monte Carlo simulation of free radical production under keV photon irradiation of gold nanoparticle aqueous solution. Part II: Local primary chemical boost

Abstract : Highlights • We calculated radical production around gold/water nanoparticle (GNP/WNP) in water. • Calculations were performed for single keV photon absorption. • In the micrometer range, radicals are overproduced by GNP compared to WNP. • In the nanometer range, radicals are overproduced by small GNP compared to WNP due to Auger electrons. • In the nanometer range, radical production is comparable for large NP.
