Abstract
Open-surface digital microfluidics refers to droplet manipulations in an open surface. Different chemical/ biological reaction protocols can easily be demonstrated in the same device by reprogramming the order of droplet manipulations. While continuous-flow or liquid-plug microfluidics within microchannels have inherently limited programmability, there is no limit of reprogrammability in open-surface digital microfluidics. Three different mechanisms for droplet manipulations are addressed in this mini-review: electrowetting-on-dielectric, magnetofluidics and wire-guide manipulations. Brief theories of surface tension and work of adhesion are addressed. Potential applications are addressed as well as their complications.
