    • Brombenzol, chloroform, and sulfuric acid are among the best suited solvants for forming a kinetically stable colloid with the nanotubes. Ethanol, acetone, and methanol (as well as water) rank among the less suited solvents and are not able to maintain the material in colloidal suspension over more than a few hours.

    • A solution of nanotubes and nanoparticles in a solvent can be viewed as a colloid, i.e., a system consisting of a dispersed phase (the nanotubes) distributed evenly throughout a dispersion medium (the solvent), see also D. Myers, Surfaces, Interfaces, and Colloids. VCH, Weinheim 1991.

    • For SEM and TEM analysis, all the material was extracted by filtering the tube- or particle-rich colloid through a 0.02 μm pore size silica filter and by washing the obtained film with distilled water to remove the remaining traces of surfactant.

    • The weight of a nanotube (and of a nanoparticle) can be roughly estimated by calculating the total surface of the graphitic planes of the tubes. The weight of an average tube with a length of 1 μm, an inner cavity of 3 nm, and a total diameter of 14 nm (as determined from a statistical analysis), amounts thus to 0.32 fg. Similarly, the weight of an average nanoparticle of 40 nm diameter and an inner cavity of 10 nm is 0.076 fg. i.e., ∼25% of the weight of a tube.
