    Abstract: A patterned article includes a carrier layer having a microstructured first major surface and an opposing second major surface. The first major surface includes pluralities of upper and lower edges spaced apart along a thickness direction of the carrier layer and defining respective upper and lower portions of the first major surface. The lower portion is disposed between the upper portion and the second major surface. The article includes a first functional layer disposed on the lower, but not the upper portion of the first major surface. The first functional layer includes at least one first micro-cut inorganic layer including a plurality of cut edges substantially coextensive with the plurality of lower edges. A method of making the patterned article is provided. Articles that can be made by transferring a functional layer from the patterned article are provided.

    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 method of fabricating a nozzle that includes casting and curing a first material using a patterned nip roller to form a first microstructured pattern of discrete microstructures, deforming at least one of the discrete microstructures; replicating the first microstructured pattern, including the at least one deformed discrete microstructure, in a second material different than the first material to make a replicated structure comprising a plurality of blind holes formed in the second material, removing second material of the replicated structure to expose tops of microstructures in the first microstructured pattern, and removing the first material from the replicated structure, resulting in a nozzle having a plurality of through-holes in the second material and corresponding to the first microstructured pattern.
