Luminescent imaging films () for fluorescent enhancement and methods of making and using the same are provided. The films () include a flexible carrier layer (, and a pattern of photonic structure () disposed on the flexible carrier layer, which is interspersed with an anti-biofouling material () to provide a pattern of analyte sites (). The pattern of photonic structure includes a patterned high-refractive-index dielectric material surface () so as to provide resonance at the excitation or emission wavelength to enhance a fluorescence signal from labeled analytes.

Nanostructured articles, materials for the nanostructured articles, and intermediate articles for use in making the nanostructured articles. The nanostructured articles can be formed on a flexible film and are useful for optical metasurface applications and possibly other applications. The articles can include nanoreplicated layers or pattern transfer layers of engineered nanostructures.

Nanostructured optical films and intermediates

Methods of making metal patterns on flexible substrates are provided. A releasable solid layer is selectively formed on a patterned surface of the flexible substrate by applying a liquid solution thereon. The releasable solid layer is transferred from the patterned surface to a transfer layer where the metal patterns are formed.

Methods of making metal patterns on flexible substrate

Materials and methods useful in forming nano-scale features on substrates, and articles such as optical films incorporating such nano-scale patterned substrates.

Materials and methods for forming nano-structures on substrates

Methods of forming an array of patterns on a substrate are provided. An array of protective tiles formed from a protectant resin is provided to cover an array of sub-regions on the substrate. An array of patterns is formed on the substrate by sequentially repeating steps (i) and (ii) for each sub-region: (i) removing the protective tile from one of the sub-regions to expose the first major surface underneath; and (ii) forming a pattern on the exposed first major surface within the one of the sub-regions.

Arrayed structured replication articles and methods

The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Dry prepregs for ceramic matrix composites are described. The dry prepregs comprise a tow or fabric of ceramic fibers infiltrated with preceramic matrix comprising low levels of an aqueous solvent. The preceramic matrix contains an inorganic portion and a binder system. Binder systems comprising a binder and a plasticizer for the binder are described.

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.

Nanopatterned films with patterned surface chemistry

Methods of making metal patterns on flexible substrates are provided. Releasable solid layer is selectively formed on a patterned surface of the flexible substrate by applying a liquid solution thereon. Metal patterns on the flexible substrate can be formed by removing the releasable solid layer after metallization. In some cases, the releasable solid layer can be transferred from the patterned surface to a transfer layer where the metal patterns are formed.

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.

A barrier film. The barrier film may include a substrate, an inorganic layer disposed on a side of the substrate, and an organic layer-by-layer structure disposed on a side of the inorganic layer, where in the organic layer-by-layer structure comprises a layer of a cationic polyelectrolyte and a layer of an anionic polyelectrolyte.
