“Trojan horse” mechanistic model of LUCS: 1, TO is mainly removed out of the cell by efflux transport limiting its access to nucleic acid targets; low fluorescence (Fpre) is observed; 2, light is applied inducing ROS production that alters efflux and/or other cell functions; 3, massive entry of TO triggers increase in fluorescence emission (Fpost).
