Abstract:
1. A microfluidic channel device including a microfluidic channel configured to receive and move a droplet, where the droplet includes at least two analytes, the microfluidic channel device comprising: a substrate including a substrate surface; an array of drive electrode assemblies disposed upon the substrate surface, the drive electrode assemblies being arranged along a path, each drive electrode assembly including: a reference electrode configured to face the second stationary phase layer surface of the drive electrode assemblies and separated from the substrate surface by a distance defining the microfluidic channel; and at least one of the drive electrode assemblies includes a second stationary phase layer including a first stationary phase layer surface configured in contact with the second dielectric layer surface and including a second stationary phase layer surface, the second stationary phase layer comprising a second material, different from the first material, the second material configured to partition a second analyte from the droplet as the droplet is moved over the second stationary phase layer, so that at least some of the second analyte is separated from the droplet and the at least some of the second analyte remains partitioned in the second stationary phase layer when the droplet is moved from the second stationary phase layer, and where the second analyte is different from the first analyte.
