Abstract

The vibrational spectroscopy in the IR region will be used to assess the interaction of analytes with metallic nanoparticles (gold or silver), complementing the Raman spectroscopy and allowing a detailed spectroscopic evaluation of the systems to be studied. Currently, it is worth to mention, the IQ-UNICAMP does not have an FTIR spectrometer operating in the 200-30 cm-1 range. The acquisition of such equipment will be of great value for the project development, but also to the IQ-UNICAMP community, once it will be made available in our multi-user facilities. This equipment will include accessories to operate using the ATR mode (Attenuated Total Reflection) in a wide spectral range thereby allowing obtaining spectra of thin films, studies of conformation of the organic molecules (ligands) in these films by the use of polarized light, and to appoint relations with the optical detection efficiency of the devices to be prepared.
