ABSTRACT:
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.
