The invention also includes modified chitosan polymers or oligomers produced by the novel processes, in particular modified chitosan polymers or oligomers having useful functional properties, such as base solubility and/or high viscosity.Type: GrantFiled: August 20, 1999Date of Patent: October 30, 2007Assignees: The University of Maryland Biotechnology Institute, The University of Maryland, Baltimore CountyInventors: Gregory F. Payne, Guneet Kumar

Patent number: 7252735Abstract: Method for making lignocellulosic composites by adhering lignocellulosic substrates together. A first variant of the method involves using an adhesive composition that comprises a reaction product of (i) first ingredient selected from a soy protein or lignin and (ii) at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein. A second variant of the method involves using an adhesive composition that comprises a reaction product of (i) a protein or lignin, (ii) a first compound that includes at least one amine, amide, imine, imide or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the protein and (iii) a curing agent.Type: GrantFiled: May 13, 2003Date of Patent: August 7, 2007Assignee: State of Oregon Acting by and through the Oregon State Board of Higher Education on Behalf of Oregon State UniversityInventor: Kaichang Li

Patent number: 6911227Abstract: This invention provides novel methods for the formation of biocompatible membranes around biological materials using photopolymerization of water soluble molecules. The membranes can be used as a covering to encapsulate biological materials or biomedical devices, as a “glue” to cause more than one biological substance to adhere together, or as carriers for biologically active species. Several methods for forming these membranes are provided. Each of these methods utilizes a polymerization system containing water-soluble macromers, species, which are at once polymers and macromolecules capable of further polymerization. The macromers are polymerized using a photoinitiator (such as a dye), optionally a cocatalyst, optionally an accelerator, and radiation in the form of visible or long wavelength UV light. The reaction occurs either by suspension polymerization or by interfacial polymerization.Type: GrantFiled: March 19, 2001Date of Patent: June 28, 2005Assignee: Novocell, Inc.Inventors: Jeffrey A.

Patent number: 6881789Abstract: The present invention relates to a novel biopolymer consisting of a three-dimensional cross-linked mixture of (a) a cross-linking agent, activated with an activating agent, dissolved in a aqueous solution, and (b) a recombinant protein, namely polyubiquitin. The novel biopolymer is based on the cross-linking of ubiquitin (monomeric and/or polymeric) with a cross-linking agent, preferably bifunctionalized polyethylene oxides or a polyethylene glycol of various molecular masses (MW 2000 to 35 000 kDa), dissolved in aqueous solution in adequate proportions. The novel biopolymer offers a wide range of formulations since the number of ubiquitin units and cross-linking agent can vary both in length and ratio. The novel hydrogel is also biodegradable by a specific protease and is resistant to a wide range of other proteases.Type: GrantFiled: May 29, 2001Date of Patent: April 19, 2005Assignee: Viridis Biotech Inc.Inventor: Marc Bossé
