Model analysis of NP sensitization with proton irradiation, according to (Wälzlein et al. 2014). Left: Simulated track of a 80 MeV proton across a gold NP with 2 nm radius, including all secondary electrons, performed with TRAX. Right-upper: spectra of electrons escaping the NP, as compared to the case when the NP is replaced by normal water or water with a density (ρ) equal to gold. Right-lower: corresponding dose enhancement (see text for details)
