Abstract

Label-free biosensing with silicon nanophotonic microring resonator sensors has proven to be an excellent sensing technique for achieving high-throughput and high sensitivity. However, this platform requires a fluidic component which allows the continuous delivery of the sample to the sensor surface. The use of microdroplets in a digital microfluidic system, instead of continuous flows, is one of the recent trends in the field. This technique allows micro-sized droplets to be manipulated on reconfigurable paths without any complex microfluidic structures such as channels or valves, and has great potential for high-throughput liquid handling, while avoiding on-chip cross contamination. We present the combination of these two technologies: label-free silicon nanophotonic microring resonator sensors and digital microfluidics.
