Gold nanocubic structures functionalization with organic layers

This dataset contains the XPS spectra obtained for gold nanocubes (AuNC), which were deposited at the gold electrode surface and dried. The AuNC's were first functionalized with either cysteamine in EtOH or mercaptopropionic acid in EtOH. The concentration of these compounds was 20 mM. The interaction of the functionalized with the AuNC surface was investigated. The four different sample types are as follows: CTAB - the surfactant used for AuNC solution, AuNC - bare functionalized AuNC's, C - cysteamine, T - mercaptopropionic acid. Each sample was studied twice. The low-resolution XPS spectrum was obtained, followed by high-resolution scans in C1s, N1s, O1s and Si2p energy range. The pass energy was 20 eV with an energy step size 0.1 eV. The amount of used AuNC was 10 uL in each case.
