  • Patent number: 11440269
    Abstract: The present invention is directed to a fully biodegradable material based on a plant protein. The present invention is also directed to a process method of making a gluten-based biodegradable material by a water induced flocculation step. A fully hydrated gluten dough with or without an additive or/and a filler formed from the flocculation step, which has low viscoelasticity, is further molded into an article with desired shapes under a low shear stress in a relatively low temperature range. A rigid or flexible biodegradable plastic article is obtained by removing extra water at a temperature lower than decomposition temperature of the gluten.

  • Patent number: 10228307
    Abstract: Disclosed herein are matrices for isolating a biological macromolecule from a biological sample, the matrix comprising: a biopolymer capable of binding to the biological macromolecule, wherein the biopolymer is about 0% to about 10% dissolvable in water at a pH of about 6 to about 8 and at ambient temperature but is about 10% to 100% dissolvable in a chaotropic solvent or an organic solvent, and wherein the biopolymer is not squid ring teeth protein; and a surfactant, excipient, or combination thereof. Also provided are methods of using, and kits comprising, the matrices. The disclosed matrices aid in collecting and releasing near quantitative amounts of a biological macromolecule from a biological and/or test sample.

  • Publication number: 20130313487
    Abstract: A plastic molding composition includes a raw powder, gelatin, a polar solvent, and a plasticizer. The raw powder contains at least one of a ceramic particle and a metal particle. The plasticizer reduces the minimum amount of the solvent necessary to give flowability to the composition. The plasticizer is a water-soluble or water-dispersible compound. The plasticizer has a ratio of hydroxyl number to carbon number per molecule in a range from 8% to 100%. The plasticizer is in solid or liquid form. When the plasticizer is in liquid form, the plasticizer has volatility equal to or lower than volatility of water.

  • Publication number: 20130287742
    Abstract: This invention relates to methods and compositions for preparation of silk-PEGs based biomaterials through crosslinking by chemically reacting active polyethylene glycols (PEGs) possessing different chemical groups (e.g., thiols and maleimides functionalized PEGs) that are additionally stabilized by the beta-sheet formation of silk fibroin. The crosslinked silk-PEGs biomaterials present strong adhesive properties, which are comparable to or better than the current leading PEG-based sealant, depending on the silk concentration in the silk-PEGs biomaterials. In addition, the silk-PEGs based biomaterials are cytocompatible, show decreased swelling behavior and longer degradation times, which make them suitable for hemostatic applications where the current available tissue sealant products can be contraindicated.
