Abstract
This review addresses the most relevant aspects of vibrational spectroscopies (IR, Raman and INS) applied to zeolites and zeotype materials. Surface Brønsted and Lewis acidity and surface basicity are treated in detail. The role of probe molecules and the relevance of tuning both the proton affinity and the steric hindrance of the probe to fully understand and map the complex site population present inside microporous materials are critically discussed. A detailed description of the methods needed to precisely determine the IR absorption coefficients is given, making IR a quantitative technique. The thermodynamic parameters of the adsorption process that can be extracted from a variable-temperature IR study are described. Finally, cutting-edge space- and time-resolved experiments are reviewed. All aspects are discussed by reporting relevant examples. When available, the theoretical literature related to the reviewed experimental results is reported to support the interpretation of the vibrational spectra on an atomic level.

Abstract
Gold nanoshells functionalized with a small peptide as a targeting agent were designed and synthesized for photothermal therapy of hepatocarcinoma. The nanoshells exhibited high absorption in the near-infrared (NIR) range, 800-1,100 nm, and were functionalized with 12-amino acid sequence peptides for targeting liver cancer cells. The nanoshells were characterized by Dynamic Light Scattering (DLS), Transmission Electron Microscope (TEM) and IR spectra. The functionalized gold nanoshells showed good targeting ability to liver cancer cells BEL-7404 and BEL-7402 while not to the normal healthy liver cell HL-7702, and also had a low cytotoxic activity. The fluorescence images showed that the gold nanoshells caused death to the liver cancer cells efficiently after being treated with a NIR light in vitro. These simple, stable, low cytotoxic, cancer-cell targeting gold nanoshells present a great promise as delivery agents for the selective photothermal treatment of liver cancer cells.
