  • Publication number: 20080274980
    Abstract: The present invention provides novel biocompatible macromonomers, hydrogels, methods of synthesis and methods of use thereof. The biocompatible hydrogels of the present invention are prepared using native chemical ligation (NCL), in which a thioester readily reacts with a N-terminal thiol (cysteine) through transesterification and rearrangement to form an amide bond through a five-member ring intermediate.

  • Publication number: 20080169059
    Abstract: Nano-scale or micro-scale adhesive structures comprising an array of nano-fabricated, pillars, the pillars having coated upon, or having disposed on a working surface thereof, a protein-mimetic, marine-adhesive coating. Methods of fabricating the nano-scale pillars, synthesis of the protein-mimetic coating or wet adhesive and application of the adhesive to the pillars are described.

  • Publication number: 20080149566
    Abstract: The present invention provides a surface-independent surface-modifying multifunctional biocoating and methods of application thereof. The method comprises contacting at least a portion of a substrate with an alkaline solution comprising a surface-modifying agent (SMA) such as dopamine so as to modify the substrate surface to include at least one reactive moiety. In another version of the invention, a secondary reactive moiety is applied to the SMA-treated substrate to yield a surface-modified substrate having a specific functionality.

  • Publication number: 20030087338
    Abstract: 3,4-Dihydroxyphenyl-L-alanine (DOPA) is an unusual amino acid found in mussel adhesive proteins (MAPs) that form tenacious bonds to various substrates under water. DOPA is believed to be responsible for the adhesive characteristics of MAPs. This invention relates to a route for the conjugation of DOPA moieties to various polymeric systems, including but not limited to poly(ethylene glycol) or poly(alkylene oxide) systems such as poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers.

  • Patent number: 5554670
    Abstract: An epoxy-silicate nanocomposite is prepared by dispersing an organically modified smectite-type clay in an epoxy resin together with diglycidyl ether of bisphenol-A (DGEBA), and curing in the presence of either nadic methyl anhydride (NMA), and/or benzyldimethyl amine (BDMA), and/or boron trifluoride monoethylamine (BTFA) at 100.degree.-200.degree. C. Molecular dispersion of the layered silicate within the crosslinked epoxy matrix is obtained, with smectite layer spacings of 100 .ANG. or more and good wetting of the silicate surface by the epoxy matrix. The curing reaction involves the functional groups of the alkylammonium ions located in the galleries of the organically modified clay, which participate in the crosslinking reaction and result in direct attachment of the polymer network to the molecularly dispersed silicate layers. The nanocomposite exhibits a broadened T.sub.s at slightly higher temperature than the unmodified epoxy.
