Directed assembly of multiplexed single chirality carbon nanotube devices

Herein, we present the fabrication of multiplexed single-walled carbon nanotube (SWCNT) devices, where selected chiralities were separately immobilized on one chip with single-tube precision. Each chirality was subsequently electrically measured individually. Specifically, (6,5) and (7,5) SWCNT species isolated via aqueous two-phase polymer systems, after which dielectrophoresis used to precisely control placement each chirality, along a metallic species, prepatterned electrodes single chip.
