Abstract
A method of delivering fluid can include using electro-wetting effects to pick-up, transport, and/or deliver discrete volumes of fluid. Voltage can be applied across a fluid contact area having a conductive substrate and a dielectric material with an outer surface. The outer surface can have a native interfacial surface tension state and a voltage induced second state having a reduction in interfacial surface tension. A fluid can be contacted such that a volume of fluid adheres to the outer surface of the fluid contact area when the voltage is applied. Subsequently, the voltage can be adjusted such that at least a portion of the volume of fluid is delivered to a receiving location.
