  • Publication number: 20120004339
    Abstract: 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.
    Type: Application

  • Patent number: 7144573
    Abstract: A reagent and related method for use in passivating a biomaterial surface, the reagent including a latent reactive group and a bifunctional aliphatic acid (e.g., fatty acid), in combination with a spacer group linking the latent reactive group to the aliphatic acid in a manner that preserves the desired function of each group. Once bound to the surface, via the latent reactive group, the reagent presents the aliphatic acid to the physiological environment, in vivo, in a manner (e.g., concentration and orientation) sufficient to hold and orient albumin.

  • Patent number: 7087658
    Abstract: 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.
