    This research explores applications of carbon nanotubes in energy and biomedical sciences. For applications in energy, this research reports the synthesis and characterization of one-dimensional silver nanostructures using single-wall carbon nanotubes (SWCNT) as a template material. Transmission electron microscopy (TEM) and scanning tunneling microscopy (STM) results are consistent with the formation of a one-dimensional array of silver particles on SWCNT. The correlation of the UV/Vis spectral results with those derived from the TEM and STM images analysis provides further insights into the silver nanostructures optical properties and morphology. There is evidence for the excitation of the longitudinal silver plasmon mode in the optical absorption spectra of the Ag-SWCNT dispersions, even at the lowest silver concentrations. The obtained results indicate that silver deposits on SWCNT have the potential to be light-to-energy conversion devices through the coupling of the electric field excited in arrays of plasmonic particles. In order to explore the nanotubes properties for the biomedical sciences field, single-wall and multi-wall carbon nanotubes were functionalized with amino groups. The functionalization makes possible the study of the tubes’ interaction with the myoglobin protein in aqueous solution. The UV/Vis data obtained suggests that there are protein-nanotubes interactions.
