Biomaterials FTIR analysis

A Fourier transform infrared spectroscopy (FTIR) analysis in solid phase in KBr has been performed using a Fourier transform infrared spectrometer to analyze and record the spectra before and after the modification of the biomaterial. Representative IR spectra of untreated and succinated biomaterial showed the presence of an...

XPS is another widely employed technique used to characterize the surface of (nano)biomaterials. XPS has a much smaller sampling depth (ca. 10 nm) and is, thus, a more sensitive surface analysis technique than FTIR-ATR. This is because the mean free average path of the X-ray that excites electrons in polymers for XPS is typically only 5-10 nm. XPS has been used extensively in the study of polymer composite surfaces to investigate the extent of surface modification, polymer chain mobility, contamination, and degradation processes.
