Isolation of specific small-diameter single-wall carbon nanotube species via aqueous two-phase extraction.
Aqueous two-phase extraction is demonstrated to enable isolation of single semiconducting and metallic single-wall carbon nanotube species from a synthetic mixture. The separation is rapid and robust, with remarkable tunability via modification of the surfactant environment set for the separation.
