From: Thymine/adenine diblock-oligonucleotide monolayers and hybrid brushes on gold: a spectroscopic study
Left two panels: N 1s HRXPS spectra of the A n T 15 films hybridized after rinsing with H 2 O (left) or with the H 2 O-NaOH rinsing procedures (right). The adenine portion of the decomposed spectra (red fill) can be seen to increase relative to the thymine portion (blue fill) in the films rinsed with H2O and NaOH relative to those rinsed with only H2O. Rightmost panels: Relative percentages of nitrogen signal stemming from the adenine (red) and thymine (blue) components of the films rinsed with H2O (top panel) and those rinsed with H2O and NaOH (bottom panel).
