  • Patent number: 8603452
    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.
