ABSTRACT:
The invention provides the use of novel, binary guanosine gels for simple, rapid and nondestructive solubilization of individual single walled carbon nanotubes (SWNTs) at high concentrations. The gels exhibit selectivity between metallic and semiconducting SWNTs and, further, among SWNTs with different chiralities.
