“…Such electron capture processes play a central role in plasma physics [5], astrophysics [6], environmental science [7] and radiation damage [8][9][10]. It was recently predicted that electron attachment to a species can be strongly enhanced in the presence of a chemical environment through the so called Interatomic Coulombic Electron Capture (ICEC) mechanism [11,12].…”

“…Plasmid DNA can be deposited on as urface, transported intoh igh vacuum and exposed to radiation, [28] which is then systematically varied to determine effective and absolute cross-sections for strand breaks and to study the effect of radiosensitizers such as cisplatin on the strand breakage. [7,23] The first study demonstrating electron-induced DNA strand breaks in the energy range of 3-20 eV was published by Boudaïffa et al, [25] who used plasmidD NA adsorbed on aT as ubstrate. [30] The fragmented DNA wass eparatedb y agarose gel electrophoresis (AGE) into supercoiled DNA, cyclic and linear fragments corresponding to undamaged DNA, SSBs and DSBs.…”

“…However,t he nanoscopic mechanisms of radiosensitization have only recently become clearer. [7] DEA experiments with gas-phase cisplatin showede ffective cleavage of the PtÀCl bonds inducedb ye lectrons of less than 1eV ( Figure 7b). [55] This could facilitate the DNA binding of cisplatin, which proceeds by the loss of the Cl À ligands.…”

“…Atualmente, podem ser utilizados tratamentos com radiações usando nêutrons, prótons, elétrons e fótons (SYMONDS et al, 2012;DAVIS et al 2016;SANCHE, 2016;MISHRA et al, 2017). Dependendo da profundidade em que está localizada a região que será tratada, é utilizado um tipo de feixe.…”
