Abstract
A method and apparatus are disclosed for manipulation of very small droplets of liquid, by placing the droplets on wettable positioning electrodes on a non-wettable substrate, applying voltages to the positioning electrodes to electrostatically charge the droplets, and applying voltages of opposite polarity to target electrodes, thereby attracting the droplets from the positioning electrodes toward the target electrodes. The electrodes can be on a manipulation surface or on a separate portable dispensing tool or pickup tool.
