a Schematic of the experimental setup of the dielectrophoresis of a SWCNT solution using a microelectrode array. The metallic tubes (in black) are deposited on the electrodes and semiconducting tubes are left in suspension (in white). Adapted from [182]. b Rayleigh scattered dark-field micrograph showing aligned SWCNTs (in green) and the corresponding polarized SWCNTs perpendicular to the electrodes. Adapted from [182]
