Some modem microfluidic approaches rely on the movement of discrete droplets rather than handling continuously flowing streams (see e.g. [97, 98]). In this way, flexible chemical protocols can be carried out, not unlike the traditional processing of batch systems. Especially with regard to pTAS applications, the footprint area the sample volume for fluidic handling are notably decreased. 

The solid/liquid interfacial energy is reduced on applying a voltage V between the droplet and a counter-electrode below the insulator. This decreases 0and leads to improved wetting of the solid by the droplet (dashed contour) [98] (by courtesy of RSQ.
