Water solubilization of single-walled carbon nanotubes (SWNTs) has been achieved by functionalizing the SWNT with glucosamine. The grafting of glucosamine to the nanotubes was attained by producing acyl chloride on the carboxylic groups associated with the nanotubes. Subsequently, amide bonds were formed between the glucosamine and the SWNT. This grafting results in solubility of SWNT in water, which ranges from 0.1 to 0.3 mg/mL, depending on temperature. Introduction. The solubilization of single-walled carbon nanotubes (SWNTs) has been a research goal for the past few years. Having SWNTs in solution opens a large number of possibilities. One of them is to facilitate the purification process.1-3 If the SWNT are selectively dissolved, they can
