摘要: A microbial indicator device for liquid disinfection comprises a first cavity, a source of biological activity fluidically coupled to the first cavity via a portion of a first fluidic path, a filter membrane positioned in a second fluidic path for a disinfectant, and a first coupling portion fluidically coupled to the source of biologically activity via the second fluidic path. The filter membrane has a first side and a second side, wherein the first side is in fluid communication with the first fluidic path. The filter membrane has a pore size sufficient to retain at least a portion of the source of biological activity on the first side. The device further comprises a frangible container contained in the first cavity, wherein a liquid in the container is in fluid communication with the first cavity when the container is fractured.

摘要: A recycling optical cavity is defined at least by first and second optical films and is configured to receive a test material therein. The test material is configured to emit at least a second light having a second wavelength when irradiated with a first light having a first wavelength. For at least one of s- and p-polarized incident lights incident in an incident plane, and at the first and second wavelengths: at a first incident angle, the first optical film has respective optical transmittances T11(θ1) and T12(θ1), and the second optical film has respective optical transmittances T21(θ1) and T22(θ1), wherein T11(θ1)>T12(θ1), T21(θ1), T22(θ1); and at a second incident angle, the first optical film has respective optical transmittances T11(θ2) and T12(θ2), and the second optical film has respective optical transmittances T21(θ2) and T22(θ2), wherein T21(θ2)>T11(θ2), T12(θ2), T22(θ2).

摘要: 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 R 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.

摘要: An article includes a flexible structured film with a first major surface and a second major surface, wherein a first major surface of the flexible structured film has a plurality of posts separated by land areas, and the posts have an exposed surface. An anti-biofouling layer resides in the land areas, and the anti-biofouling layer has a methylated surface. An inorganic layer is on the exposed surfaces of the posts, wherein the inorganic layer includes a metal or a metal oxide. An analyte binding layer is on the inorganic layer, wherein the analyte binding layer is chosen from a reactive silane, a functionalizable hydrogel, a functionalizable polymer, and mixtures and combinations thereof. An exposed surface of the analyte binding layer includes at least one functional group selected to bind with a biochemical analyte.

摘要: An article includes a flexible carrier film with a first major surface having an array of structures, at least a portion of which include an inorganic layer and an analyte binding layer. The analyte binding is bonded to the inorganic layer via a network of hydrocarbon linking groups, and the analyte binding layer includes at least one functional group selected to bind with a biochemical analyte. Recessed features interspersed with the structures are free of the inorganic layer and the analyte binding layer.
