  • Publication number: 20140227783
    Abstract: A novel method for building complex three-dimensional scaffolds for biomimetic applications such as in vitro organ growth, using a gelatin/sugar/water gel, ultraviolet radiation, and heat or enzyme is described. The method produces gelatin-sugar hydrogels demonstrating greater thermal stability, mechanical strength, and resistance to enzymatic degradation. The invention also provides a means to assemble the gelatin sugar hydrogel films into complex three-dimensional structures (scaffolds). To account for the native biochemical factors present in natural scaffolds, methods of conjugating such factors to the gelatin-sugar hydrogel are described. These scaffolds can then be applied for tissue culturing and organ growth. The present invention also describes a system and apparatus for constructing these complex three-dimensional scaffolds by taking advantage of the physical and chemical properties of the gelatin-sugar hydrogel.

    Abstract: The invention comprises a biological hydrogel that is chemically stabilized with non-covalent or covalent cross-links. The biological hydrogel is used to coat surfaces of materials for submersion in marine water. Molecular dissolution at the marine water-hydrogel surface prevents attachment of fouling organisms. The rate of dissolution can be controlled by both the concentration of the biopolymer in the hydrogel and the nature and concentration of cross-linker used. Additional components, either molecular or particulate, can be added to the biological hydrogel before or after cross-linking for enhanced properties.

    Abstract: According to principles of this invention, flour can be used as a filler for either an oil-based or PEG-based paintball fill material. In one embodiment of the present invention, a paintball fill material preferably comprises flour. More particularly, a paintball according to principles of the present invention can comprise a gelatin capsule defining an interior chamber which, upon formation of the paintball, houses a fill material. The fill material can comprise, for instance, 1%-65% polyethylene glycol, 25%-45% flour, and up to 0.5% dye, with the balance water. Accordingly, unlike conventional paintballs, the paintball fill material of the present invention preferably contains flour rather than starch to reduce the amount of polyethylene glycol required for the fill material. In alternative formulations, an oil can be used in addition to, or instead of, polyethylene glycol. According to another aspect of the present invention, the gelatin capsule for the paintball can also utilize flour in its composition.

  • Patent number: 6706467
    Abstract: An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and a colloidal particle dispersed material phase at a volume fraction of at least 0.01, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. The present invention enables increasing the concentrations of a coating fluid containing gelatin and dispersed sub-micron colloidal materials, reducing the size of the sub-micron colloidal materials in such a coating fluid, and/or including higher molecular weight gelatin in such a coating fluid without detrimentally increasing the viscosity of such fluids. The invention further enables reducing the viscosity of an aqueous coating fluid containing gelatin and dispersed insoluble colloidal material, without needing to reduce the concentration of gelatin or colloidal materials, increase the size of the sub-micron colloidal materials, and/or reduce the molecular weight of the gelatin.

  • Patent number: 6589326
    Abstract: An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and gelatin hardener at a level from 1-200 effective &mgr;mole hardener per gram of coating fluid, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. Relative improvements are obtained in reducing the rate of chemical gelation of a coating fluid containing gelatin and a hardener, without the need for chemically modifying functional groups of the gelatin. The invention further enables an increase in coating fluid concentration, increase in the fluid viscosity, reduction in the ratio of added anionic polymer to gelatin, and/or increase in the pH of a coating fluid containing gelatin and a hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid.

  • Patent number: 6506577
    Abstract: The synthesis of moisture-resistant adhesive polypeptides, conditions for their use, and conditions for controlling characteristics of the crosslinked matrix are disclosed. By specifically manipulating the conditions under which these networks are formed, the characteristics of the networks may be precisely regulated. These manipulatable adhesive networks are water-based, show exceptional bonding capabilities toward wet materials (including biological tissues), and have a variety of biotechnological applications.

  • Patent number: 6447593
    Abstract: Coating foundry sand with a thin layer of an oxidation-promoting catalyst. Preferred catalysts comprise ferric and cupric oxides. The catalysts promote the oxidation of any polymeric binder or residues admixed with the sand. The sand is coated by wetting the grains with a solution of a catalyst precursor, drying the sand and baking the sand in air to convert the precursor to the catalyst.
