Abstract:
1. A device for detecting a target analyte in a fluid sample, the device comprising: a reaction chamber, wherein the reaction chamber comprises internal surfaces, a binding agent and a probe agent, the probe agent comprising a binding partner and a vehicle, wherein the binding partner is bound to the vehicle, wherein the target analyte in the fluid sample can react with the binding agent or the binding partner, wherein the vehicle comprises a plurality of copies of an activating agent; a detection chamber, wherein the detection chamber comprises a detecting agent, wherein the activating agent can activate the detecting agent; and a fluid passageway between the reaction chamber and the detection chamber, wherein the device is adapted to move the reacted fluid sample from the reaction chamber to the detection chamber through the fluid passageway via capillary action, and wherein the presence of the target analyte in the fluid sample at a concentration results in a change in the amount of probe agent that moves with the reacted fluid sample to the detection chamber, wherein the change is detectable in the detection chamber and dependent on at least a threshold of the concentration.
