XPS STUDIES ON AMORPHOUS AND NANOSTRUCTURED BIOMATERIALS SURFACE AND THEIR BIOFLUID INTERFACE.

X-ray photoelectron spectroscopy (XPS) is extensively used to characterise the surface of materials used in bioengineering. Its ability to characterise both the elemental composition and structural characteristics of the surface makes it particularly useful, as it can identify the functional groups present on the surface of any material and implicitely give insight into biointerfacial interactions. The paper summarizes some XPS results obtained on compact and porous materials with potential biomedical applications, before and after their interaction with simulated body fluids.
