Apparatus and methods are provided for liquid manipulation utilizing electrostatic field force. The apparatus is a single-sided electrode design in which all conductive elements are embedded on the first surface on which droplets are manipulated. An additional second surface can be provided parallel with the first surface for the purpose of containing the droplets to be manipulated. By performing electrowetting based techniques in which different electrical potential values are applied to different electrodes embedded in the first surface in a controlled manner, the apparatus enables a number of droplet manipulation processes, including sampling a continuous liquid flow by forming individually controllable droplets from the flow, moving a droplet, merging and mixing two or more droplets together, splitting a droplet into two or more droplets, iterative binary mixing of droplets to obtain a desired mixing ratio, and enhancing liquid mixing within a droplet.
