Electrowetting forces depend largely on the cleanness of the substrates, since even small traces of impurities may notably change the wetting behavior [99], This certainly can be controlled under laboratory conditions, but may experience limitations under dirty real-world applications. Further limitations on the droplet volume are given by the geometric constraints of the electrode chamber which needs to be wetted at the floor and ceiling. 

Dielectrophoretic forces depend on the polarizibility of species, rather than on movement of charges [99]. This allows the movement of any type of droplet being immersed by a dielectrically distinct immiscible carrier medium. Since dielectric forces are generated by spatially inhomogeneous fields, no mechanical actuation is required. In addition to this, dielectrophoretic droplet movement benefits from the general advantages given by droplet microfluidic, i.e. discrete, well-known very small volumes, no need for channels, avoidance of dead volumes and more.
