Abstract: Diagnostic devices including a first metallic or (co)polymeric substrate, a second metallic or (co)polymeric substrate opposite the first (co)polymeric substrate and an elongate substantially planar porous substrate positioned between the first metallic or (co)polymeric substrate and the second metallic or (co)polymeric substrate, and a multiplicity of edge seals formed between the first and second metallic or (co)polymeric substrates around at least a portion of the perimeter of the porous substrate such that the first and the second metallic or (co)polymeric substrates together substantially surround and encapsulate the porous substrate. An optional compressible layer is preferably positioned between at least one of the first metallic or (co)polymeric substrate and the porous substrate and/or the second metallic or (co)polymeric substrate and the porous substrate. The diagnostic devices are suitable for qualitative or quantitative analysis of a sample fluid. Methods of making the diagnostic devices also are described.

Abstract: Methods and apparatuses for screen or stencil printing a pattern on a substrate are provided. The substrate (2) has its major surface in contact with a first major surface (112) of a stencil shell (111) having apertures (116). A coating material is disposed onto the second major surface (114) of the stencil shell (111) to flow through the apertures (116) to contact the substrate (2), where the coating material is at least partially cured. The substrate (2) is separated (C) from the first major surface (112) of the stencil shell (111) after the curing (142) and a pattern (42) of the at-least-partially-cured coating material is formed on the substrate (2).

Abstract: An optical construction includes a reflective polarizer and an optically diffusive film disposed on the reflective polarizer. The reflective polarizer includes an outer layer including a plurality of first particles partially protruding from a first major surface thereof to form a structured major surface. A first optically diffusive layer is conformably disposed on the structured major surface. The optically diffusive film includes a second optically diffusive layer including a plurality of nanoparticles dispersed therein, and a structured layer including a structured major surface. For a substantially normally incident light and a visible wavelength range from about 450 nm to about 650 nm and an infrared wavelength range from about 930 nm to about 970 nm, the second optically diffusive layer has an average specular transmittance Vs in the visible wavelength range and an average specular transmittance Is in the infrared wavelength range, where Is/Vs ≥ 2.5.

Abstract: A diagnostic device includes a sensor stack with multiple panels of a porous material disposed in planes parallel to one another and in face-to-face contact with each other. At least a portion of the panels of the porous material include hydrophobic regions and hydrophilic regions configured to provide a sample flow path for migration of a fluid sample through the sensor stack from one panel to another in the hydrophilic regions. A wicking layer is on a major surface of the sensor stack.

Abstract: Diagnostic devices for quantitative or qualitative analysis of a sample fluid including an analyte include at least two portions made from a hydrophilic material. The planar portions are stacked on each other and each occupy a different and substantially parallel plane to form a three-dimensional structure. At least one of the planar portions includes a hydrophobic region formed by applying a low surface energy material that extends through a thickness of the substrate portion from a first major surface to a second major surface thereof. The hydrophilic regions in the overlying substantially parallel substrate portions can be aligned with each other such that a fluid is passively transported between adjacent hydrophilic regions to provide a sample flow path between adjacent substrate portions.

Abstract: The present disclosure relates to adhesive article that include a stretch releasable adhesive and topographical, engineered elements on, within, or partially embedded in a surface of the adhesive. The engineered elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the adhesive, whereby the article can be initially positioned or rotated by sliding the surface of the projections across the wall surface. Under certain conditions, the article may even be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely against the desired mounting surface, develop additional tack and holding power after sufficient pressure is applied.
