Diamagnetic levitation of droplets and/or particles of pico-femtoliter volume was analyzed. A levitation based microfluidic processor was demonstrated to process droplets/particles with up to a billion times smaller volume than in a typical microfluidic devices. It was found that the levitated particles can be positioned with up to 300 nm accuracy and precisely rotated and assembled. The results show that, force can be applied to the droplets/particles via magnetic, electric and gravitational fields with up to femto-Newton accuracy and potential energy can be controlled with up to 0.2 zepto.
