Abstract
An apparatus providing a fluidic cartridge including a first and second substrate and an intermediate interlayer is disclosed. The intermediate interlayer is sealedly interfaced between the first and second substrates to form therein a plurality of channels of capillary dimensions. The apparatus further includes an open reservoir, a pump chamber and a reaction chamber. The open reservoir and reaction chamber are each connected to the pump chamber through the channels. The open reservoir and reaction chamber are in fluid communication with each other via the channels. The apparatus further provides a fluid flow controlling structure, formed in the fluidic cartridge, which restricts a flow of a fluid through the reaction chamber to one direction. The apparatus further provides a linear actuator for providing a pumping action in the pump chamber to pump the fluid to recirculate from the reaction chamber to the open reservior via the channels and pump chamber.
