This chapter describes some of the most important spectroscopic methods to
study the materials surface. Special IR and Raman configurations providing information
from the surface will be reviewed highlighting the main advantages and/or drawbacks
for their applications in the study of biomaterials. Additionally, some examples are
presented to demonstrate their usefulness for the surface characterization of materials
for biomedical applications as well as to understand the complexity of the chemical
interactions between biomaterial surface and biological molecules.
Keywords: Infrared spectroscopy, raman spectroscopy, organic-inorganic
interaction, calcium phosphates, surface characterization.
