| Resumo: | [EN] In this paper we study the ability of Surface-Enhanced Optical Techniques (Raman, IR and fluorescence) in the detection of pollutants such as polycyclic aromatic hydrocarbon. We have combined the optoelectronic properties of nanostructured coinable metals, leading to a remarkable sensitivity enhancement, and the selectivity imposed by a host molecule functionalization of the metal substrate. Host molecules of different nature and origin were tested in relation to their ability to interact with PAHs: synthetic and natural. The information resulting from this study can be applied in the design of chemical sensors for the detection of these important pollutants. |
