    Abstract: A detection article including at least one fluid control film layer having at least one microstructured major surface with a plurality of microchannels therein. The microchannels configured for uninterrupted fluid flow of a fluid sample throughout the article. The film layer including an acquisition zone wherein portions of the plurality of microchannels draw the fluid sample into the plurality of microchannels through openings in the microchannels at least by spontaneous fluid transport. The film layer also including a detection zone in uninterrupted fluid communication with the acquisition zone along the microchannels with the detection zone including at least one detection element that facilitates detection of a characteristic of the fluid sample within at least one microchannel of the detection zone. The detection article may be formed from a plurality of film layers that are stacked to form a three-dimensional article. The detection zone may include a plurality of detection elements, which may be all the same, may be all different or may have some different and some the same. In addition, the detection elements may be variations of the same element. The detection elements may include hardware devices, assay reagents and/or sample purification materials.

    Abstract: A receptor medium with a sheet having an embossed imaging surface as one maj or surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The embossed mediu m unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained. Methods of making and using the inkjet receptor medium are also disclosed.
