1. An iDEP device for sorting single-walled carbon nanotubes by length, the iDEP device comprising:
an inlet channel including a constriction, wherein a cross-sectional area of the inlet channel reduces at the constriction;
a center channel;
at least one side channel, wherein the inlet channel splits into multiple channels after the constriction, the multiple channels including the center channel and the at least one side channel;
an electrode positioned in the center channel; and
an electrical field source configured to apply an electrical field between the electrode and a proximal end of the inlet channel,
wherein the inlet channel diverges from the constriction into the center channel and the at least one side channel.
