    • 3 (15 mL) was ultrasonicated with a probe-type sonicator (30-50W) for 60 min under ice cooling. After diluting the mixture with deionized water (100 mL), the crude cut nanotube was filtered though PTFE membrane filter (Advantec, pore size = 0.1 μm). It was then washed with deionized water until the pH of the filtrate become neutral. The mixture was purified with gel permeation chromatography (Sephadex G-25, eluted with water). Average length of the cut SWNT as determined by SEM was 330.6 ± 60.9 nm.

    • The cut SWNT (0.98 mg) was dispersed in an aqueous solution (0.5 mL) of 1 (3.85 mg, 17 μmol). EDC (3.43 mg. 18 μmol), HOBt (2.31 mg, 17 μmol), and triethylamine (5.23 mg, 51 μmol). After rigorously stirring the mixture for 72 h at room temperature, it was dialyzed (cut off Mw = 8000) against deionized water to remove the low-molecular weight species.

    • Formation of the network structure depends on the sample preparation. When the aqueous solution of the Gal-SWNT/PNA was dropped on mica and was allowed to evaporate under reduced pressure at ambient temperature, such network structures were not obtained. It is therefore possible that the developed network structures are produced during the freeze-drying process.

    • The apparent average diameters of the aggregate in aqueous solution were determined by DLS. The diameter in the absence of PNA (175 ± 54 nm) was increased to 321 ± 54 nm after the addition of PNA (60 μM, incubated for 12 h).
