摘要： This invention provides a method of irreversibly immobilizing an enzyme into polyurethane coatings. This invention also provides for an enzyme-containing coating having a degree of immobilization of the enzyme of approximately 100%. The synthesis of waterborne polyurethane coatings in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix. The distribution of immobilized enzyme as well as activity retention are homogeneous within the coating. Decreasing ECC hydrophobicity, via the use of a less hydrophobic polyisocyanate prepolymer during polymerization, significantly enhanced the intrinsic activity of the ECC.

摘要： A polymer formed by controlled radical polymerization includes groups that can be modified after controlled radical polymerization to form a radical. The polymer can be the reaction product of a controlled radical polymerization of radically polymerizable monomers, wherein at least one of the radically polymerizable monomers includes at least one group that can be modified after the controlled radical polymerization to form a radical. A compound includes a first group that is stimulated upon application of energy to the molecule to tether the molecule to a surface or to another polymer chain and a second group comprising a controlled radical polymerization initiator functionality. A block copolymer includes at least a first segment to impart a predetermined functionality to a target surface and at least a second segment including functional groups to interact with the targeted surface to attach the block copolymer to the surface. The first segment can free of functional groups that interact with the surface to attach the block copolymer to the surface.

摘要： A biocidal article, includes a surface including a plurality of polymers covalently attached to the surface. The polymers include biocidal cationic groups. The polymers have a molecular weight distribution or polydispersity less than 3. A grafting density of the polymers on the surface is controlled, average degree of polymerization of the polymers is controlled and repeat units of the polymers are- chosen to provide a predetermined charge density arising from the cationic groups. A method of analyzing biocidal activity of biocidal surface agents includes the steps: attaching a plurality of chemical entities to one or more surfaces so that at least one physiochemical property is varied, each of the chemical entities comprising at least one biocidally active component; and exposing the chemical entities to at least one biological agent to determine the effect of the at least one physiochemical property upon biocidal activity. The biocidal activity can, for example, be antibacterial activity or sporicidal activity. The at least one physiochemical property can, for example, be varied in a preferably systematic manner.

摘要： A method for joining nanotubes end-to-end, includes contacting the nanotubes with a joining fluid. The joining fluid has at least one property that is different from at least one property associated with ends of the nanotubes. In one embodiment, the method further includes contacting the nanotubes with a first, treating fluid and removing the bulk first fluid before the nanotubes are contacted with the joining fluid. The joining fluid is immiscible in the treating fluid to effect end-to-end joining of the nanotubes.

摘要： A device for removal of at least a portion of carbon dioxide from an aqueous fluid includes at least one membrane (e.g. a hollow fibre) through which carbon dioxide can pass to be removed from the fluid and immobilized carbonic anhydrase on or in the vicinity of a first surface of the membrane to be contacted with the fluid such that the immobilized carbonic anhydrase comes into contact with the fluid. The first surface exhibits carbonic anhydrase (CA) activity of at least 20% of maximum theoretical activity of the first surface of the membrane based on monolayer surface coverage of carbonic anhydrase in the case that the carbonic anhydrase is immobilize on the first surface. The surface of the membrane is activated before the CA is bonded to it.

摘要： A composition includes at least one antioxidant moiety and at least one UV-absorbing moiety. The antioxidant moiety and the UV-absorbing moiety are maintained in proximity to each other. The UV-absorbing moiety and the antioxidant moiety can, for example, be attached to a common entity. The antioxidant moiety and the UV-absorbing moiety can, for example, be covalently attached within a single molecule. The UV-absorbing moiety can be attached sufficiently closely to the antioxidant moiety to enhance the stability of the antioxidant in an environment in which photooxidation can occur. In one embodiment, the UV-absorbing moiety is attached to the molecule to be juxtapositioned to the antioxidant moiety.
