Abstract:
The present invention provides high-density arrays including mask layers and methods of manufacturing the same. The arrays are formed on a polymeric substrate and include a mask layer. Various linking agents, linking agent coatings, and/or reactants may be provided on the mask layer. Where present, the linking agents and reactants preferably operate together to capture a desired analyte which can then be detected based on an electromagnetic signal, e.g., fluorescence, that is emitted by the analyte in response to excitation energy incident on the array. With the mask layer in place, the signal-to-background ratio provided by the arrays can be increased.
Abstract:
A slurry comprises a ferromagnetic fiber having an aspect ratio of 10 to 10,000 and an organic liquid medium that is unreactive with the metal fibers.The metal fibers are provided by preparing a mixture comprising a thermally unstable metal complex compound, comprising at least one ferromagnetic metal, in a liquid medium, applying energy to said mixture in the presence of an externally applied magnetic field to decompose said complex compound, and isolating the deposited metal fibers.Articles are provided by the impregnation of metal fibers of the invention into and onto a porous substrate.
Abstract:
The present disclosure describes methods for making shaped polymeric materials. Methods are provided for making shaped polymeric materials from a precursor composition that contains a polar solvent and a polymerizable material that is miscible with the polar solvent. The precursor composition is at least partially polymerized in a mold.
Abstract:
Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.
Abstract:
Articles are provided for the detection of cells in a sample. The articles include a release element. The release element comprises an encapsulating agent and a cell extractant. The release element controls the release of the cell extractant into a liquid mixture containing the sample. Methods of use are also disclosed.
Abstract:
The present disclosure provides rewettable asymmetric membranes and methods of forming rewettable asymmetric membranes. More specifically, methods are provided for forming rewettable asymmetric membranes having a copolymer and a polymerized material retained within the porous substrate.
Abstract:
Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.
