(A) TTF rupture tumor cell membrane by accumulating all polar molecules and dipoles in the cleavage furrow during the interdivision stage. (B) Boron-10 in tumor cells, radiated with thermal neutrons, releases high linear energy transfer (LET) α and 7Li particles. Both alpha particles and the lithium ions produce closely spaced ionizations in the immediate vicinity of the reaction, leading to a selective tumor cell killing.
