Microfluidics and Bio-Mems

Droplet-based, Digital, Centrifugal Microfluidics

Droplet-based digital microfluidics is a topic with growing importance to biological, chemical, and health-science fields. The high fedility and magnificent reagent economy of such systems are unparalleled. There are, however, elementary challenges related to actuation and sensing in terms of system scalability, and these challenges are addressed within this chapter. In particular, a new digital microfluidics multiplexer is shown to overthrow simultaneous on-chip micro drop motion addressability issues and terminate droplet involvement challenges. At the same time, an integrated folded-cavity optical sensor come up with highly localized and sensitive probing of internal fluid refractive indices. The complete system offers improved micro drop motion and sensing abilities for future lab-on-a-chip technologies.
