  • Patent number: 10280204
    Abstract: A method of manufacturing a biopolymer optical device includes providing a polymer, providing a substrate, casting the polymer on the substrate, and enzymatically polymerizing an organic compound to generate a conducting polymer between the provided polymer and the substrate. The polymer may be a biopolymer such as silk and may be modified using organic compounds such as tyrosines to provide a molecular-level interface between the provided bulk biopolymer of the biopolymer optical device and a substrate or other conducting layer via a tyrosine-enzyme polymerization. The enzymatically polymerizing may include catalyzing the organic compound with peroxidase enzyme reactions. The result is a carbon-carbon conjugated backbone that provides polymeric “wires” for use in polymer and biopolymer optical devices. An all organic biopolymer electroactive material is thereby provided that provides optical functions and features.
