Abstract
X-ray Photoelectron Spectroscopy (XPS), which is known as
Electron Spectroscopy for Chemical Analysis (ESCA), is a powerful
research tool for the study of the surface of solids. The technique
is 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. There are impartial reasons for low
involvement of XPS into investigations of biologically related
objects. In this presentation successful examples of XPS studies of
bio-related specimens will be presented. In particular, 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
self-assembling layer characterization will be considered on the
examples of thiols on Au and aryl diazonium molecules on Si(111).
