PROBLEM TO BE SOLVED: To provide a color image sensor, an optical sensor and a photoelectric transducer, which employ protein and can stably be used over a long period of time, and to provide methods of manufacturing these. SOLUTION: In the method, a blue-light photoelectric transducer is formed by fixing zinc substituted cytochrome c552 13 on a gold electrode 11 through a self-assembled monolayer 12. Alternatively, a blue-light photoelectric transducer is formed by fixing cytochrome c552 on the gold electrode through the self-assembled monolayer and bonding the cytochrome c552 with a fluorescent protein which absorbs blue light. These photoelectric transducers are used as a blue-light photoelectric transducer of the color image sensor or the optical sensor. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling the conductivity type of a protein semiconductor which allows easy control of the conductivity type of the protein semiconductor, and also provide a method for producing a protein semiconductor and a method for producing a p-n junction using the same.SOLUTION: The conductivity type of a protein semiconductor is controlled by controlling the electric charge of the total amino acid residues, and thus a p-type protein semiconductor or an n-type protein semiconductor is produced. Then, a p-n junction is produced by using the p-type protein semiconductor and the n-type protein semiconductor. The electric charge of the total amino acid residues is controlled by substituting one or more acidic, basic or neutral amino acid residues contained in the protein by amino acid residues having properties different therefrom, chemically modifying one or more acidic, basic or neutral amino acid residues contained in the protein, or controlling the polarity of a medium surrounding the protein.

SOLUTION: The liquid-uncontacting all-solid-state protein photoelectric conversion element has a structure in which a solid protein layer 13 including an electron transport protein is sandwiched between an electrode 11 and an electrode 12. The solid protein layer 13 is immobilized on both the electrode 11 and the electrode 12. The solid protein layer 13 contains no liquid such as water. The solid protein layer 13 includes a monomolecular film or multi-molecular film of the electron transfer protein. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a color imaging device and a photosensor that are stably usable for a long period with high definition and high sensitivity, and to provide a molecular device which is suitably used therefor. SOLUTION: A photoelectric conversion element is formed by immobilizing cytochrome c552 13 on a gold electrode 11 via a self-assembled molecular monolayer 12 and coupling an electron transfer protein 14 having a photoelectric conversion function to the cytochrome c552 13. Alternatively, a photoelectric conversion element for green light or blue light is formed by immobilizing zinc-substituted cytochrome c552 or zinc-modified porphyrin cytochrome c552 on the gold electrode. The color imaging device or photosensor is constituted using those photoelectric conversion elements. COPYRIGHT: (C)2011,JPO&INPIT
