摘要： A method for moving an aqueous droplet comprising providing an electrokinetic device including a first substrate having a matrix of electrodes, wherein each of the matrix electrodes is coupled to a thin film transistor, and wherein the matrix electrodes are overcoated with a functional coating comprising: a dielectric layer in contact with the matrix electrodes, a conformal layer in contact with the dielectric layer, and a hydrophobic layer in contact with the conformal layer; a second substrate comprising a top electrode; a spacer disposed between the first substrate and the second substrate and defining an electrokinetic workspace; and a voltage source operatively coupled to the matrix electrodes. The method further comprises disposing an aqueous droplet on a first matrix electrode; and providing a differential electrical potential between the first matrix electrode and a second matrix electrode with the voltage source, thereby moving the aqueous droplet.
