ABSTRACT:
A sensor for the detection of an analyte includes a first reagent in one section of the housing and at least a second reagent in another section of the housing. The sensor also includes a reservoir of a carrier fluid (that is, a liquid or a gas) within the housing. A release mechanism of the sensor is in operable connection with the reservoir so that when the release mechanism is activated, the carrier fluid is released from the reservoir. The carrier fluid mobilizes the second reagent to contact the first reagent with the second reagent. The interaction of the first reagent and the second reagent is affected by the presence or absence of the analyte to cause a measurable change of state within the sensor.
