Abstract
A versatile flow cell front-end (104) for storing and delivering reagents, test samples, and other transportable materials within an optically-based integrated sensor device (100), where management of those materials is controlled via electrical connections (110, 114) within the optically-based integrated sensor device is disclosed, including an inlet chamber (118) formed within the flow cell, a sensing chamber (116) formed within the flow cell, an electrical interface (114) formed within the flow cell, a conduit (122) adjoining the inlet and sensing chambers, another conduit (124) adapted to dispose of fluid in the sensing chamber, and a fluidic control member (126) instantiated along the conduit and responsively coupled to the electrical interface.
