摘要： A method of detecting organic vapors is described. More particularly, the method involves the use of an analyte sensor that contains a polymeric material having a relatively large intrinsic porosity and that is capable of fluorescence in the visible region of the electromagnetic spectrum. The method further includes exposing the analyte sensor to an environment that may contain an organic vapor and monitoring the analyte sensor for a change in a fluorescence signal. Although the organic vapor itself typically does not fluoresce in the visible wavelength range, presence of an organic vapor can alter the fluorescence signal of the analyte sensor.

摘要： An optically-responsive multilayer reflective article is formed by applying a dilute solution or suspension of metallic nanoparticles to an optically-responsive detection layer. The solution or suspension is allowed to dry to form a semicontinuous liquid- or vapor-permeable light-reflective layer that will permit a liquid or vapor analyte to pass through the light-reflective layer to cause an optically-responsive change in the detection layer in the presence of the analyte.

摘要： A sorbent media protective device includes an enclosure having a gas inlet, gas outlet and a thin-film multilayer indicator. The thin-film multilayer indicator is proximate sorbent media that can sorb a vapor of interest flowing from the gas inlet towards the gas outlet. The indicator includes a porous detection layer whose optical thickness changes in the presence of the vapor, located between a semireflective layer and a reflective layer permeable to the vapor. With equilibration at the applied vapor concentration between at least a portion of the media and the vapor, the vapor can pass through the reflective layer into the detection layer and change the detection layer optical thickness sufficiently to cause a visibly discernible change in the indicator appearance if viewed through the semireflective layer.
