The study deals with the primary species, ejected electrons, and guanine radicals, leading to oxidative damage, that is generated in four-stranded DNA structures (guanine quadruplexes) following photo-ionization by low-energy UV radiation. Performed by nanosecond transient absorption spectroscopy with 266 nm excitation, it focusses on quadruplexes formed by folding of GGG(TTAGGG)<sub>3</sub> single strands in the presence of K<sup>+</sup> ions, <b>TEL21/K<sup>+</sup></b>. The quantum yield for o ...[more]
