Figure 8From: Evaluating protocols and analytical methods for peptide adsorption experiments Characteristic XPS surveys and elemental spectra of K 10 deposited on different inorganic substrates. Clean substrates were incubated for 24Â h in a 0.5Â mM peptide solution (10Â mM sodium phosphate buffer, pHÂ 7) at room temperature. Surveys (a), and elemental spectra of the N 1s (b) and C 1s (c) regions are shown as raw XPS intensities.Back to article page
