Abstract
A microfluidic device includes a substrate and a non-valve capillary mechanism. At least a reservoir and one or more channels leading to the reservoir are formed within the substrate. The non-valve capillary mechanism is within the reservoir, and prevents fluid delivered to the reservoir from wicking from the reservoir into the channels.
