▎ 摘　　要

NOVELTY - A composite nanostructured protein membrane is obtained by physical process of ultrasonication for decrosslinking/crosslinking of eggshell protein membranes or fibrillar proteins. USE - Composite nanostructured protein membrane is used as flexible organic electrode for manufacture of energy storage device such as flexible or non-solid-state supercapacitor and/or sensing of biomolecules, gases, dyes, pesticides and other environmental contaminants, and as electrode and/or platform for immobilization and detection of nucleic acid chains of pathogenic agent, proteins and antibodies (all claimed). ADVANTAGE - The composite nanostructured protein membrane produces organic electrode through a simple, fast and low cost process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of the composite nanostructured protein membrane, which involves adding a commercial aqueous suspension or performing chemical synthesis of in-situ polymerization of the conductive polymer, during or after the process of preparation by ultrasound of the composite protein membrane to obtain desired properties; and use of the composite nanostructured protein membrane as an electrode and/or a platform for immobilization and detection of nucleic acid chains of pathogenic agent based on biorecognition of specific molecular interactions, with the probe to be used for biorecognition which is being a single-stranded strand of nucleic acid with specific sequence corresponding to the pathogen of interest, and immobilization and detection of proteins and antibodies from a biorecognition of specific molecular interactions, with the probe to be used for biorecognition which is being a specific antigen or antibody corresponding to the disease of interest.
