  • Patent number: 8338532
    Abstract: The invention further relates to multichromophores, which may be conjugated polymers, and methods, articles and compositions employing them as described herein. In some aspects, the invention relates to methods, articles and compositions for the detection and analysis of biomolecules in a sample. Provided assays include those determining the presence of a target biomolecule in a sample or its relative amount, or the assays may be quantitative or semi-quantitative. The methods can be performed on a substrate. The methods can be performed in an array format on a substrate, which can be a sensor. In some embodiments, detection assays are provided employing sensor biomolecules that do not comprise a fluorophore that can exchange energy with the cationic multichromophore.

  • Patent number: 8309623
    Abstract: The disclosed is a biodegradable copolymer, an amphiphilic diblock copolymer, composed of a hydrophilic segment and a hydrophobic segment. The hydrophilic segment is an endcapped PEG or derivatives thereof. The hydrophilic segment is a random polymer polymerized of lactone or cyclic C3-C6 molecule and lactic acid/glycolic acid. There is no coupling agent between the hydrophilic and hydrophobic segments, and the biodegradable copolymer is formed by one-pot ring-opening polymerization. The biodegradable copolymer can be dissolved in water to form a thermosensitive material having a phase transfer temperature of 25 to 50° C., thereby being applied to biological activity factor delivery, tissue engineering, cell culture and biological glue.

  • Patent number: 8283413
    Abstract: The present invention is drawn to an aqueous emulsion composition. The composition includes an aqueous phase and a hydrophobic phase dispersed in the aqueous phase, which includes a plurality of hydrophobic monomers. The monomers are acid-functionalized and hydrophobic, with less than 10% solubility in water. In one aspect, the monomers can be aromatic. Such monomers can be polymerized with other monomers to form latex particulates. A latex can include latex particulates dispersed in an aqueous fluid medium. In one embodiment, latex particulates can include from about 0.1 wt % to about 25 wt % of polymerized hydrophobic acid-functionalized monomer, and at least one other polymerized film-forming monomer. The latex can be formulated as an ink-jet ink.

  • Publication number: 20120116013
    Abstract: A method of curing a coating composition and a method of forming a cured coating on an automobile component are provided. The coating composition comprises a radical polymerizable compound and an organoborane-amine complex having an organoborane initiator, an amine blocking agent, and water. The method of curing the coating composition comprises the steps of combining the organoborane-amine complex, the radical polymerizable compound, and water to form the coating composition. Carbon dioxide is introduced into the coating composition or into a composition including at least one of the organoborane-amine complex, the radical polymerizable compound, and water prior to forming the coating composition. Carbonic acid is formed in situ within the coating composition through reaction of the water and carbon dioxide. The organoborane-amine complex is de-complexed with the carbonic acid thereby separating the organoborane initiator and the amine blocking agent.
