1. A biosensor cartridge configured to removably engage a bioassay system, the biosensor cartridge comprising:
- a flow cell including inlet and outlet ports and a flow channel that extends therebetween, the flow cell also including a substrate field in fluid communication with the flow channel, the substrate field having a plurality of reaction sites distributed along a length and a width of the substrate field, the flow channel forming a common space that extends over the substrate field along the length and the width such that the plurality of reaction sites are exposed to the common space;
an activity detector coupled to the flow cell and including an array of pixels, the pixels configured to detect activity along the substrate field that is indicative of desired reactions;
first and second side surfaces, the first side surface including the inlet and outlet ports, the second side surface comprising electrical contacts that are communicatively coupled to the activity detector.

Abstract
A flow cell including inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween. The flow channel includes a diffuser region and a field region that is located downstream from the diffuser region. The field region of the flow channel directs fluid along reaction sites where desired reactions occur. The fluid flows through the diffuser region in a first flow direction and through the field region in a second flow direction. The first and second flow directions being substantially perpendicular.
