Progress in micro- and nanotechnologies depends on our capability of manipulating and interacting with microscopic particles and nanosize material. A promising approach towards this goal is the use of electric fields, which are the dominant forces at the molecular length scale. One technique for trapping nanoparticles in solution uses an externally controlled electric field, generated by two electrode pairs, to counteract the Brownian motion of a single, selected particle. Unlike other trapping tools, such as optical tweezers or magnetic tweezers, this approach scales favorably with particle size, down to the level of a single molecule. However, it depends on real-time …
