Abstract: A system and methods for sterilizing or disinfecting articles, particularly the hollow internal areas of medical instruments are disclosed. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power is connected to the plasma generator for applying an electron energy density between the electrode and the shield. A source of gas comprising water vapor, oxygen and nitrogen provides a flow of gas between the electrode and the shield, to form a plasma containing acidic and/or oxidizing species. In the exemplary system, the temperature at the shield's surface is 0.05 eV/molecule of the gas. Also disclosed is a method for disinfecting an article contaminated with a bio-film or spores, by exposing the contaminated article to the plasma for an exposure time sufficient to achieve at least 2-log10 reduction in colony forming units.

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: The present disclosure provides articles including an adhesive layer; a film layer bonded to the adhesive layer having a microstructured surface including numerous capillary channels; and a cover layer disposed on the capillary channels and attached to the adhesive layer. The adhesive layer is hydrophobic and includes an aperture for fluid (e.g., sweat) collection from a skin surface. The film layer also includes an aperture that overlaps the adhesive layer aperture to direct collected fluid to the capillary channels of the microstructured surface, which have a hydrophilic surface. Optionally at least one indicator chemistry can be present in the channels to facilitate optical (e.g., visual) determination of total fluid volume and/or concentration of at least one analyte in the fluid as a function of time.

CPC classification number: G01N15/0806 , G01N15/0826
Abstract: An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.
