X-ray photoelectron spectroscopy of γ-ray-irradiated single-stranded DNA

The effects of γ -ray irradiation on herring sperm single-stranded DNA have been studied by using X-ray photoelectron spectroscopy (XPS) in the view of the bonding configurations and the structural modifications. The significant changes in the hydrogen, carbon, nitrogen, and phosphorous bonding ener...

Summary:The effects of γ -ray irradiation on herring sperm single-stranded DNA have been studied by using X-ray photoelectron spectroscopy (XPS) in the view of the bonding configurations and the structural modifications. The significant changes in the hydrogen, carbon, nitrogen, and phosphorous bonding energies, as revealed by the XPS analysis, indicate that electron transfers result in the creation of radicals and in DNA strand breaks.
