Abstract: Patterned arrays of shortened singlewalled carbon nanotubes(sSWNTs) on gold were prepared using a surface reaction method. Under the existence of a condensation reagent, dicyclohexyl carbodiimide (DCC), sSWNTs terminated with carboxylic groups were found to react with the NH2(CH2)11SH selfassembled monolayers (SAMs) on gold readily, but could rarely be adsorbed on a CH3terminated surface. Thus by using a patterned surface with both NH2 and CH3 groups, sSWNTs were immobilized only on NH2 areas, resulting in a patterned array of sSWNTs.

Key words: Shortened single-walled carbon nanotubes (s-SWNTs), Surface reaction, Patterned assembly, Gold surface
