Abstract
An EWOD device includes a first and second substrate assemblies, and a spacer that spaces apart the first substrate assembly from the second substrate assembly to define a channel between them. The spacer defines fluid input ports that are in fluid communication with the channel, and the spacer is configured for directing fluid from the fluid input ports into the channel. The spacer has a combed spacer configuration to define the fluid input ports, including alternating teeth that extend into the channel from a base region, and the teeth isolate adjacent fluid input ports from each other. The spacer may contact only a portion of the first and second substrate assemblies to form a spacerless region within the EWOD device, and the spacer includes regions that are in contact with both the first and second substrate assemblies and extend into the channel to define a cell-gap of the channel.
