摘要： A grafting reagent and related method of using the reagent to form a polymeric layer on a support surface, and particularly a porous support surface, in a manner that provides and/or preserves desired properties (such as porosity) of the surface. The reagent and method can be used to provide a thin, conformable, uniform, uncrosslinked coating having desired properties onto the surface of a preformed, and particularly a porous, polymeric substrate. The method includes the steps of a) providing a porous support surface, b) providing a nonpolymeric grafting reagent comprising a photoinitator group, c) providing one or more polymerizable monomers adapted to be contacted with the surface, in the presence of the grafting reagent, and to be polymerized upon activation of the photoinitiator; and d) applying the grafting reagent and monomer(s) to the surface in a manner, and under conditions, suitable to coat the surface with the grafting reagent and to cause the polymerization of monomers to the surface upon activation of the grafting reagent.

摘要： A method of forming a polymer layer on a support surface by the use of a coating agent and polymerizable compounds. The coating agent provides photoreactive groups adapted to attach the agent to the surface, as well as photoreactive groups adapted to remain unattached to the surface, and thus serve as photoinitiators for the activation of polymerizable compounds in order to form a polymer layer thereon. Also provided are coating agents, per se, as well as a method of using such agents and the resultant surfaces and devices fabricated therefrom.

摘要： A chemical linking agent is formed of a di- or higher functional photoactivatable compound having at least one group that is charged under the conditions of use in order to provide improved water solubility. The linking agent contains two or more photoreactive groups in order to allow the agent to be used as a cross-linking agent in aqueous systems. The charged group can be provided by a radical that includes one or more salts of organic acids, onium compounds, or protonated amines, (and optionally one or more additional photoreactive groups) and the photoreactive groups can be provided by two or more radicals that include an aryl ketone. The onium compound can provide a quaternary ammonium, sulfonium or phosphonium group. A surface can be coated with a target molecule such as a synthetic polymer, carbohydrate, protein, lipid, nucleic acid, drug, vitamin, cofactor or dye by forming an aqueous solution of the linking agent and the target molecule, placing the solution in contact with the surface and activating the photoreactive groups of the linking agent to cross-link the target molecule to the surface.

摘要： A photoactivatable reagent useful as a chain transfer reagent for providing a semitelechelic polymer having one or more terminal photoactivatable groups. The reagent provides one or more photoactivatable groups and one or more sulfhydryl (or other chain transfer) groups, the photoactivatable and chain transfer groups optionally being joined together by a spacer group. The reagent can be used to prepare a polymer by serving to initiate the polymerization of ethylenically unsaturated monomers. The reagent itself becomes an integral part of the resultant polymer, thereby providing the polymer with a terminal photoactivatable nature. The method provides a number of benefits, including the ability to provide homogeneous photoactivatable polymer compositions, e.g., in terms of the uniform location of the photogroup(s) on the terminal portion of each polymer molecule and the ability to build a desired nonpolar quality, and in turn improved surfactancy, into otherwise polar polymers.
