A matrix electrode-controlling device for driving a droplet according to this aspect of the present invention comprises a substrate, a dielectric layer positioned on the substrate, a plurality of control electrodes positioned in the dielectric layer in a matrix manner, and a ground electrode positioned at a predetermined position around the control electrodes without generating electromagnetic shielding effect. The control electrodes in the same row are electrically connected to form a plurality of lateral controlling rows and the control electrodes in the same column are electrically connected to form a plurality of longitudinal controlling columns, and the droplet is driven to move on or above the dielectric layer by biasing the ground electrode to the ground voltage and applying a predetermined voltage to one of the controlling rows and/or to one of the controlling columns to undergo the predetermined assaying operation.
