Abstract: A droplet actuator configured to improve the throughput of droplet operations in a detection spot of the droplet actuator and/or to reduce carryover problems is provided. The droplet actuator may include electrodes configured for effecting droplet operations transporting droplets on a surface; a sensor arranged in proximity to one or more of the electrodes establishing a detection window on the surface for detection of one or more properties of one or more droplets on the surface; wherein the electrodes may establish at least two pathways for transport of droplets into the detection window.
