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.
