Dr.Fan fabricates nanowires, nanorings, nanodiscs, and 3-D nanosuperstructures. She also invented the "electric tweezers" based on the combined AC and DC electric fields. The electric tweezers can transport nanoparticles with independently controlled orientation and transport direction along arbitrary trajectories. Two nanowires (6 mm in length and 300 nm in diameter) with initial separation distance of 180 micrometers can be transported towards each other and connected tip to tip. The precision is at least 300 nm. Nanowires can also rotate seamlessly after transportation. The rotation of the nanowires can be instantly switched on or off with controlled rotation speed (to at least 26000 rpm for a free rotating nanowire), chirality, and total angle of rotation.
