Desorption of small ionic fragments from oligonucleotides induced by low energy carbon ions


The degradation of oligonucleotide films containing differing base sequences induced by 4 keV C ions has been studied experimentally. The oligonucleotides were deposited onto a gold coated stainless steel substrate and the anions and cations released from the films were analyzed by a quadrupole mass spectrometer. The total ion desorption yield was recorded… (More)
