72. To obtain the elemental analysis data with a good S/N ratio, we had to select somewhat larger bundles that would be formed during the drying process, otherwise we could not obtain the reliable elemental analysis data.
73. It should be noted that the CLSM image reflects the fluorescence of the composite, so that the size (or width) of the composite cannot be estimated by this fluorescence method.
74. Synthetic polymers that are covalently attached to carbon nanotubes tend to form regular structures on the carbon nanotube template. See: (a) Czerw, R.; Guo, Z.; Ajayan, P.

84. Recently, Coleman and Ferreira presented a simple and general model that describes the ordered assembly of polymer strands on nanotube surfaces, the energetically favorable coiling angles being estimated to be 48°-70°: Coleman, J. N.; Ferreira, M. S. Appl. Phys. Lett. 2004, 84, 798. This theoretical approach is partly complementary to our present results, but their single-chain wrapping system cannot be directly compared to our two-chains wrapping system.
85. Electron tomography (ET) is a useful technique for reconstructing an object from a series of projections acquired by TEM. Recent development of fully digitized and automated TEM has enabled us to achieve the three-dimensional ET, not only to determine the size and distribution of objects but also to provide information about the morphology of them in the nanometer order. Three-dimensional structure was reconstructed by processing a series of projections by combination of IMOD and Amira. See: (a) Frank, J.
