    • (b) Reaction step A follows the procedure in the above reference. For step B, typically the substrate is immersed in a mixed solution of 500 μL of sodium tetraborate aqueous buffer (0.1 M, pH 8.5) and 400 μL of dimethylforamide with 1 mg of 2. The concentration of the aqueous solution of carbonaceous materials 3 in step C could be varied over a wide range without affecting the surface immobilization process. The reaction in step B typically takes 12 h, and the surface assembly in step C is finished within 2 h for both SWNHs and SWNTs.

    • note
    • Because of the presence of the SDS surfactant and the high aspect ratio of SWNTs, compared with that of SWNHs, the process of the surface immobilization of SWNTs is different, and the surface density of SWNTs is not as high as that of SWNHs. (The assembly of both SWNHs and SWNTs is finished within 2 h, and the surface density is not increased afterwards.)
