Patent number: 11292002Abstract: Disclosed herein is a surfactant additive, ethylenediamine tetrakis(ethoxylate-block-propoxylate) tetrol with 16 ethylene oxide repeat units and 18 propylene oxide repeat units (known by its trade name as Tetronic 90R4) used as a droplet-additive, or to coat DMF driving electrode surfaces which dramatically improves the capability to work with high-protein-content liquids (e.g., whole blood) on digital microfluidic chips. This surfactant prevents protein adsorption and fouling of DMF electrode surfaces to an extent that was heretofore impossible. Specifically, this surfactant allows for the manipulation of droplets of undiluted whole blood for >1 hour per electrode (>1 50 times better than what is possible for any known additive). This improvement in handling high protein content media will revolutionize blood-based diagnostics on digital microfluidic platforms.Type: GrantFiled: March 31, 2017Date of Patent: April 5, 2022Assignee: THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTOInventors: Ryan Fobel, Alphonsus Hon-Chung Ng, Aaron Ray Wheeler, Man Ho Stephen Ho

Patent number: 6652920Abstract: A method of coating a substrate comprises immersing a surface portion of a substrate in a first phase comprising carbon dioxide and a coating component comprising a polymeric precursor; then withdrawing the substrate from the first phase into a distinct second phase so that the coating component is deposited on the surface portion; and then subjecting the substrate to conditions sufficient to polymerize the polymeric precursor and form a polymerized coating.Type: GrantFiled: July 29, 2002Date of Patent: November 25, 2003Assignees: North Carolina State University, The University of North Carolina at Chapel HillInventors: Ruben G. Carbonell, Joseph M. DeSimone, Brian J. Novick

Patent number: 6610464Abstract: A process for patterning a non-rigid membrane in a closed gap environment including the optional step of applying a solvent to the non-rigid membrane, applying a layer of an energy-sensitive composition to the non-rigid membrane, spinning the non-rigid membrane, inverting the non-rigid membrane with the layer of an energy-sensitive composition, spinning the inverted non-rigid membrane, re-inverting the non-rigid membrane, and spinning the re-inverted, non-rigid membrane. As a result of the inverting step and the inverted spinning step, the layer of an energy-sensitive composition does not cause the non-rigid membrane to sag and the resulting layer of energy-sensitive composition is substantially uniform in thickness. The energy-sensitive composition may be a photoresist, such as a chemically amplified photoresist.Type: GrantFiled: May 24, 2001Date of Patent: August 26, 2003Assignee: Agere Systems Inc.Inventor: Leonidas E.

Patent number: 6509098Abstract: Methods are provided for the fabrication of hydrophilic coatings on hydrophobic surfaces. In one embodiment, a polyethylene oxide (PEO) coating is fabricated on the surface of a polymeric material by contacting the surface with a methacrylic acid or acrylic acid monomer. The monomer first is reacted, for example by irradiation with an electron beam, to polymerize and covalently attach the monomer to the surface, to improve the hydrophilicity of the polymeric material. A coating of PEO molecules is subsequently attached to the polymer surface by hydrogen bond complexation. The PEO coating then may be covalently grafted onto the surface, for example, by irradiation grafting with an electron beam. The covalent grafting of a coating of the methacrylic or acrylic monomers to the surface greatly improves the wettability of the surface, and facilitates the covalent or non-covalent attachment of a coating of PEO to the polymer surface.Type: GrantFiled: November 17, 1995Date of Patent: January 21, 2003Assignee: Massachusetts Institute of TechnologyInventors: Edward W. Merrill, Susan S. Allgor, Gladys C. Leung

Patent number: 6506459Abstract: A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.Type: GrantFiled: December 20, 2001Date of Patent: January 14, 2003Assignee: 3M Innovative Properties CompanyInventors: Richard M. Flynn, Mark W. Grenfell, George G. I. Moore, John G. Owens

Patent number: 6461689Abstract: The specular gloss of a polyurethane wear layer of a surface covering is controlled by controlling the thermal conditions of a substrate before and after it is coated with a liquid polyurethane and by controlling the termal conditions of the liquid polyurethane before it is coated on the substrate. The liquid polyurethane is photo-curable or radiation-curable and it contains a matting agent. Changes in specular gloss are attained without changing the composition of the polyurethane or the conditions of photo-curing or radiation curing.Type: GrantFiled: August 31, 2000Date of Patent: October 8, 2002Assignee: Domco Tarkett Inc.Inventors: Martin Gauthier, Claude Charest, René Ménard, Jean-François Courtoy
