    Abstract: A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.

    Abstract: A device for growing microorganisms. The device includes a body member comprising a self-supporting, water-proof substrate having upper and lower surfaces; a hydrophobic spacer element adhered to the upper surface of the substrate forming side walls to retain a predetermined amount of liquid in contact with the substrate, wherein the hydrophobic spacer element has a hole therein; a fluid control film in the hole of the hydrophobic spacer element; a cover sheet having an inner-facing surface and an outer-facing surface, the cover sheet adhered to at least a portion of the body member; and a substantially dry, first microbial growth nutrient composition disposed on a portion of the inner surface of the cover sheet; a first adhesive composition adhered to the first microbial growth nutrient composition; and a cold-water-soluble first hydrogel-forming composition adhered to the first adhesive composition.

    Abstract: The present disclosure provides articles having conformal layers and methods of making such articles. An article includes a first polymeric layer having a substantially planar major surface and an opposing major surface bonded to a second polymeric layer. One major surface of the second polymeric layer is conformal to the first polymeric layer while the opposing major surface defines a cavity having at least one wall. The second polymeric layer also has a channel connecting the cavity to at least one edge of the second polymeric layer or to the planar surface of the first polymeric layer. A surface of the cavity exhibits an advancing contact angle with water of less than 90 degrees. A method includes obtaining a tool having protruding features; disposing a first polymer on the protruding features; disposing a second polymer on the first polymer; and applying compression to the polymeric tooling, the first polymer, and the second polymer at an elevated temperature to form the article. The articles can be formed to have small cavities for use as precision fluidic devices, such as blood glucose testing strips.

    Abstract: A condensation management system includes an elongated flexible film configured to be stretched under tension between a first film support and a second film support. The film includes first and second ends that extend laterally across a width of the film. The film includes first and second sides that extend longitudinally between the first and second film ends. The film has a concave surface and an opposing convex surface extending between the first and second sides of the film. Microchannels are disposed in at least one of the concave surface and the convex surface. The microchannels induce a predetermined radius of curvature in the concave and convex surfaces of the film when the film is stretched longitudinally between the first and second film supports.
