  • Patent number: 10631973
    Abstract: Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF/CCN2, or cells.
    Type: Grant
    Filed: March 10, 2017
    Date of Patent: April 28, 2020
    Assignee: Washington University
    Inventors: Stephen Linderman, Guy Genin, Stavros Thomopoulos, Kollbe Ahn, Victor Mark Birman
  • Patent number: 10280342
    Abstract: A compound of formula (I): can be used as a monomer for making an underwater adhesive polymer. The compound of formula (I) can be prepared using eugenol as a starting material.
    Type: Grant

  • Patent number: 9441112
    Abstract: Compositions useful for preparing pressure sensitive adhesives, coatings, and/or films are provided, along with methods of making and using the same. The compositions are made from renewable, plant-based materials. The compositions comprise plant oil triglycerides that are polymerized and crosslinked to yield polymer matrices. Plant-based carriers and/or tackifiers can be used in the invention, including epoxidized plant oil triglycerides, acrylated epoxidized plant oil triglycerides, and dihydroxylated plant oil triglycerides. Natural tackifiers such as rosin esters and terpenes can also be used in the compositions. Dihydroxylated plant oil triglyceride tackifiers for use in biobased and synthetic adhesives are also provided.

  • Patent number: 8877951
    Abstract: Superparmagnetic acid-functionalized nanoparticle catalysts are provided along with methods of using the same to protonate an oxygen atom of a carbon-oxygen bond. Particularly, the catalysts comprise a nanoparticle having a ferromagnetic core surrounded by a metal oxide shell. The nanoparticle is at least partially coated with an acid-functionalized siloxane compound. The acid-functionalized nanoparticles may be used to catalyze any number of reactions that can be catalyzed in the presence of protons. The ferromagnetic core permits the nanoparticle catalyst material to be separated from the reaction medium through application of a magnetic field and reused.
