Nanowire Transport, Assembly, and Rotation in Suspension by AC Electric Fields (JHU Ref 4530)
|
|
A variety of low dimensionality entities, such as nanospheres, nanodisks, nanowires, and nanotubes, have recently been explored due to their unique attributes and capabilities to bind chemical and biological targets. Nanowires posses a large aspect ratio and geometrical shape, and multi-component nanowires have allowed for tuning of their physical, chemical and electrical properties. JHU Researches have developed a method of manipulating nanowires. They have shown that metallic nanowires, regardless of being magnetic or non-magnetic, can be efficiently driven to align, to chain, and to accelerate in a direction parallel and perpendicular to their orientation. Nanowires have been demonstrated to concentrate and assemble onto designated places into various two dimensional (2-D) patterns and three dimensional (3-D) scaffolds, and to disperse on a microscopic scale. Furthermore, the nanowires can be compelled to rotate with high angular velocities and with a specific chirality. Utilizing a single rotating nanowire, JHU Researchers have developed a new type of micro-motor. This may find a large volume of application in micro electromechanical systems (MEMS).
