Sketch of possible mechanisms involved in the enhancement of ion beam effects by radio-enhancing NP. A) Direct traversal: enhanced electron production from Auger electrons and Auger cascades. B) Plasmon excitation from a close distance and following coupling with strong electron production. C) Electrons produced in the primary track impinging the NP, which produces additional electron emission. D) Enhancement of radiolytic species due to a catalytic effect of the NPs, promoting the dissociation of excited water molecules, amplifying radical production. These mechanisms may take place anywhere along the track. Insets: Monte Carlo simulations of secondary electron tracks in a 20 nm segment at different depths of the ion track
