Abstract

A droplet actuator comprising a substrate comprising an electrode coupled to a voltage source, wherein the droplet actuator is configured such that when voltage is applied to the electrode, an electrostatic energy gradient is established at a surface of the substrate which causes a droplet to be transported in a direction established by the energy gradient. Related methods and other embodiments are also provided.
