Electron inelastic mean free paths for carbon nanotubes from optical data

We present a simple model dielectric response function for both bulk and individual carbon nanotubes based on a parameterization of experimental optical data and analytic dispersion relations that account for dimensionality and linewidth broadening. The model is used to calculate electron inelastic mean free paths over a broad energy range of interest to various applications.</ p the rationale behind using Ads for such applications. Due to the modular nature of the Ad capsid, multiple therapeutic or diagnostic modalities, such as the addition of magnetic resonance imaging  contrast agents, radiation sensitizers and antigenic peptides for vaccines, can be incorporated by modifying different sites on the viral capsid. These types of particles have a tremendous potential to increase the sensitivity and specificity of therapies.
