Abstract
Carbon nanotubes are functionalized in a broadly applicable manner. According to an example embodiment of the present invention, single-wall carbon nanotubes (SWNTs) are noncovalently functionalized. The functionalized SWNTs are highly versatile, being useful for a variety of implementations, including for the immobilization of molecules, for circuit arrangements, molecular electronics and for molecular sensors. In addition, stable suspensions of functionalized SWNTs in solutions can be achieved, as well as the self-assembly of nanotubes with unperturbed sp2 structures and thus their electronic characteristics.
