  • Patent number: 11292002
    Abstract: 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.

  • Patent number: 6652902
    Abstract: Boronic acid containing polymers are used to form bioinert gels and multilayer surface structures. These polymers form crosslinked hydrogels, which are highly swollen in water. The crosslinking can either be chemical or physical. Water soluble polymers containing boronic acid groups, such as phenylboronic acid (PBA), can be physically crosslinked by mixing the polymers in water with other polymers containing hydroxyls or carboxylic acids. Alternatively, surfaces can be treated by stepwise incubation with a solution of the boronic acid containing polymer, followed by incubation with a solution of a diol or carboxylic acid containing polymer. Many successive layers can be generated, increasing the thickness of the formed structure at each step.

  • Patent number: 6652920
    Abstract: 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.

  • Patent number: 6610464
    Abstract: 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.

  • Patent number: 6509098
    Abstract: 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.

  • Patent number: 6461689
    Abstract: 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.
