We propose a surface condensation method for assembling single-walled carbon nanotubes (SWNTs) on gold. The as-prepared long and randomly tangled SWNTs were cut into short pipes by chemical oxidation, allowing the nanotubes to be terminated by carboxyl functionalities. A surface condensation reactio
## Abstract **Summary:** This manuscript describes a new simple method to disperse single wall carbon nanotubes (SWNTs) in various organic solvents. The method is based on using amphiphilic block copolymer micelles as a dispersant. We have found that the stabilization of SWNTs by block copolymer mi
