    Abstract: The present disclosure provides a multilayer article. The multilayer article includes a) a microfiltration membrane substrate, the microfiltration membrane substrate having a first major surface; and b) a first layer having a first major surface and a second major surface disposed opposite the first major surface. The first major surface of the first layer is directly attached to the first major surface of the microfiltration membrane substrate. The first layer includes a first polymeric binder and a plurality of acid-sintered interconnected first silica nanoparticles arranged to form a continuous three-dimensional porous network. The multilayer article further includes c) a second layer attached to the second major surface of the first layer. The second layer includes i) a metal coating or ii) a composite coating comprising a second polymeric binder and at least one of metal nanoparticles or metal nanowires.

    Abstract: Luciferin-containing substrates are provided including a substrate and luciferin dried on the substrate. The luciferin-containing substrate is free of a detectable amount of reactive luciferase. The substrate is optionally a nonwoven substrate. Monitoring devices are also provided. The monitoring devices include a test element having a test portion, a detection reagent comprising luciferase, a luciferin-containing substrate, and a container having a first end with an opening and a second end opposite the first end. The container is configured to receive the test portion and configured to be operationally coupled to an analytical instrument. The detection reagent and the luciferin each are capable of participating in one or more chemical reaction that results in the formation of a detectable product.
