Light-Actuated Digital Microfluidics (Optoelectrowetting) [BPN552]
The ability to quickly perform large numbers of chemical and biological reactions in parallel using low reagent volumes is a field well addressed by droplet-based digital microfluidics. Compared to continuous flow-based techniques, digital microfluidics offers the added advantages such as individual sample addressing and reagent isolation. We are developing a Light- Actuated Digital Microfluidics device (also known as optoelectrowetting) that optically manipulates nano- to micro-liter scale aqueous droplets on the device surface. The device possesses many advantages including ease of fabrication and the ability for real-time, reconfigurable, large-scale droplets control (simply by altering the low-intensity projected light pattern). We hope to develop Light-Actuated Digital Microfluidics into a powerful platform for lab-on-a-chip (LOC) applications.
