    Abstract: A method of detecting microorganisms in a test sample is provided. The method includes the steps of: a) incubating the test sample with a growth media to form an incubated sample, wherein the growth media includes an enzyme substrate and the enzyme substrate includes an enzymatically hydrolysable group and a fluorescent group, wherein microorganisms present in the test sample include an enzyme that hydrolyzes the hydrolysable group from the fluorescent group to form a fluorescently detectable product, wherein the fluorescently detectable product has both an acidic and basic species; b) exciting the fluorescently detectable product with light having a wavelength of Exλiso for a time sufficient for the fluorescently detectable product to emit light, wherein Exλiso is the absorbance isosbestic point of the fluorescently detectable product; and c) detecting light emitted at a wavelength of Emλ1.

    Abstract: Assay devices are provided including a receptacle having a sample entry port; a plunger disposed within the receptacle; at least one reagent; a membrane attached to a first surface of the plunger; a wick providing capillary force; and a detection zone. The membrane includes a target conjugate zone in which affinity components are disposed. Capture compounds are immobilized in a detection zone, which is located between the target conjugate zone and the wick. A method of detecting a target analyte is also provided, including providing the assay device; providing a sample suspected to contain a target analyte; adding the sample onto the device; allowing the sample to travel along the membrane until the sample reaches the detection zone; immobilizing the target analyte through reaction of the target analyte with the capture compounds; reacting the immobilized target analyte with a reagent to generate a detectable signal; and detecting the generated signal.

    Abstract: An azido-containing monomer, a polymer containing monomeric units derived from the azido-containing monomer, and various articles containing a substrate and a coating layer of the polymer positioned on the substrate are provided. The azido groups, which are pendant groups of the polymer, can undergo a click chemistry reaction with an unsaturated compound such as those having a terminal -C≡CH group, a dibenzocyclooctyne-containing group, an unsaturated bicyclic olefinic group, or an amido group. The click chemistry reaction can be used to covalently attach a fluorescent or bioactive compound to the polymer.

    Abstract: A self-contained biological sterilization indicator comprises: a housing; bacterial spores comprising, and/or capable of producing, an enzyme capable of catalyzing cleavage of an enzyme substrate; and a frangible container containing a composition, wherein the composition comprises the enzyme substrate, wherein if the frangible container is broken the composition will contact the bacterial spores to form a mixture having an initial pH in the range from 6.0 to 9.0. The enzyme substrate comprises a fluorinated 4'-alkylumbelliferyl α-D-glucopyranoside represented by the structural formula (I) wherein one of R 1 and R 2 is F and the other is H, and R 3 is an alkyl group having from 1 to 12 carbon atoms. A biological sterilization indicator comprising a kit containing isolated components comprising (i) bacterial spores comprising, and/or capable of producing, an enzyme capable of catalyzing cleavage of the enzyme substrate and a method of assessing efficacy of a sterilization process are also disclosed.
