Abstract
Apparatus, methods, and systems for automated liquid droplet manipulation include an open droplet supporting surface. An actuator can translate the surface in space with at least one degree freedom of movement to influence movement of one or more droplets on the surface. In one embodiment, the surface is patterned with areas that attract the droplets and interstitial areas that repel the droplets to enhance transport of droplets. For example, for water-based droplets the attracting areas can be hydrophilic and the repelling hydrophobic. In one embodiment, the repelling areas are superhydrophobic. Electromechanical movement of the surface avoids expensive and complex microfluidic fabrication and components, and avoids electrowetting requirements.
