| Abstract | X-ray Photoelectron Spectroscopy (XPS) is a powerful research tool for the
study of the surface of solids. The technique becomes a widely-used for
studies of the properties of atoms, molecules, solids, and surfaces. The
main success of the XPS technique is associated with studies of the physical
and chemical phenomena on the surface of solids. These investigations were
limited by relatively-simple inorganic reactions and not many
biologically-related objects were approached by XPS.
In this presentation successful examples of XPS studies of bio-related specimen will be presented. In particularly, the systematic XPS investigation of four peptide-silane and peptide-silane hybrid sol-gel thin films prepared under biologically benign conditions will be reported. This work demonstrates a use for XPS to characterized biologically-inspired surfaces, providing critical information on peptide coverage on the surface of the materials. The chemical shift is discussed. The other example is the self-assembling layers of thiols on Au surface. The usage of Angle resolved XPS is demonstrated. The third discussed example is DNA associated single-walled carbon nanotubes.
