Assembly of 1D Nanostructures into Sub‐micrometer Diameter Fibrils with Controlled and Variable Length by Dielectrophoresis

A dielectrophoresis method for manipulation, alignment, and assembly of 1D nanostructures is reported. Processed carbon nanotubes dispersed in water are assembled into micro‐electrodes and fibrils of variable and controllable length from ∼ 1 μm to over 1 cm (see Figure). The method allows of parallel fabrication, and the fibrils could find applications as probes for scanning probe microscopes, electrodes, and conducting wires.
