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: A method for manufacturing an electronic device includes providing a substrate with a first major surface having a microchannel, wherein the microchannel has a first end and a second end; dispensing a conductive liquid in the microchannel to cause the conductive liquid to move, primarily by capillary pressure, in a first direction toward the first end of the microchannel and in a second direction toward the second end of the microchannel; and solidifying the conductive liquid to form an electrically conductive trace electrically connecting a first electronic device at the first end of the microchannel to a second electronic device at the second end of the microchannel.

Abstract: The present disclosure relates to adhesive article that include a first, stretch releasable adhesive and patterned adhesive elements on, within, or partially embedded in a surface of the adhesive. The adhesive elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the first adhesive, whereby the article can be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the final location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the first adhesive can contact and adhere more permanently to the wall. Thus, a stretch releasable adhesive articles of the present disclosure can move freely relative to the desired mounting surface, while developing additional tack and holding power after sufficient pressure is applied.

Abstract: A pattern of microchannels is formed on a major surface of a substrate on the side opposite an adhesive surface thereof. Through holes extend through the substrate and are connected to the pattern of microchannels. Solid circuit dies are adhesively bonded to the adhesive surface of the substrate. The contact pads of the solid circuit dies at least partially overlie and face the through holes. Electrically conductive channel traces are formed to electrically connect to the solid circuit dies via the through holes.

Abstract: Luminescent imaging films (100) for fluorescent enhancement and methods of making and using the same are provided. The films (100) include a flexible carrier layer (1109, and a pattern of photonic structure (120) disposed on the flexible carrier layer, which is interspersed with an anti-biofouling material (130) to provide a pattern of analyte sites (132). The pattern of photonic structure includes a patterned high-refractive-index dielectric material surface (123) so as to provide resonance at the excitation or emission wavelength to enhance a fluorescence signal from labeled analytes.
