  • Patent number: 9587141
    Abstract: The present invention provides a process of coating at least a portion of a substrate surface comprising contacting the surface with hydrogen cyanide monomeric units under conditions permitting polymerisation of the hydrogen cyanide monomeric units to form a polymer that coats the surface. Also provided is a substrate coated by a polymer according to the claimed process. Also provided is a method of forming a hydrocyanic acid-based hydrogel, the method comprising co-polymerisation in a solution, the solution comprising hydrogen cyanide monomer units and co-monomers.
    Type: Grant

  • Publication number: 20050089578
    Abstract: Methods for treating diseased or damaged tissue in a subject are disclosed, involving administering to said subject at a site wherein diseased or damaged tissue occurs, cells of a type(s) normally found in healthy tissue corresponding to the diseased or damaged tissue, and/or suitable progenitor cells thereof, in association with bioresorbable beads or particles and optionally a gel and/or gel-forming substance. Where the cells and/or suitable progenitor cells thereof are chondrocytes, embryonic stem cells and/or bone marrow stromal cells, the methods of the invention are suitable for treating, for example, articular cartilage degeneration associated with primary osteoarthritis.
