Abstract: 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.

Abstract: An article includes a flexible carrier film with a first major surface having an array of structures, at least a portion of which include an inorganic layer and an analyte binding layer. The analyte binding is bonded to the inorganic layer via a network of hydrocarbon linking groups, and the analyte binding layer includes at least one functional group selected to bind with a biochemical analyte. Recessed features interspersed with the structures are free of the inorganic layer and the analyte binding layer.

Abstract: A PTSM-coated expandable microsphere comprises a polymer shell enclosing an interior volume containing at least one blowing agent. The polymer shell has an outer surface with photothermal susceptor material disposed on at least a portion thereof. If heated to at least one temperature greater than 25° C., each of the expandable microspheres expands, but does not rupture, the polymer shell by a sufficient amount to at least double the interior volume. A markable comprises a substrate and a viewable layer secured thereto. The viewable layer comprises a binder material retaining the PTSM-coated expandable microspheres. A method of marking a markable article comprises imagewise exposing the PTSM-coated expandable microspheres of the markable article to at least sufficient electromagnetic radiation to cause the PTSM-coated expandable microspheres to expand thereby creating a predetermined image. A marked article preparable according to the method is also disclosed.

Abstract: Reaction mixtures, foams prepared from the reaction mixtures, articles containing the foams, and methods of making the foams are provided. The polymeric material in the foam is formed from a polymerizable composition that includes a di(meth)acrylate oligomer and a monomer having a single ethylenically unsaturated group. The foams are highly filled (e.g., at least 60 volume percent of the foam is the filler) and can be thermally conductive. Although the foams contain a large amount of filler, the foams can be compressed at least 40 volume percent with an applied pressure of 50 pounds per square inch (345 kiloPascals).

Abstract: Open cell foam compositions are provided including a thermoplastic polymeric matrix and at least one filler. In some embodiments of the foam compositions, the filler includes nepheline syenite. Methods of making the foam compositions are described, the methods including (a) obtaining a composite materials containing a first thermoplastic polymer having a filler component and a blowing agent distributed therein; (b) coextruding the composite material with a second thermoplastic polymer and a third thermoplastic polymer to form a three-layer composition, wherein the three-layer composition includes a middle layer comprising an open cell foam formed from the foam composition, and the middle layer is disposed between the first and the second outer layers formed from the second and the third thermoplastic polymers, respectively; and (c) separating the middle layer from each of the first and the second outer layer. The first thermoplastic polymer is different from the second and the third thermoplastic polymers.
