PROBLEM TO BE SOLVED: To provide a bio-fuel cell in which a fuel solution for drinking is not contaminated and is easy to be recovered.SOLUTION: In a bio-fuel cell 1 of the present invention, an absorber 30 is attached to a cell 10. A fuel solution 50 of the cell 10 is absorbed and held by the absorber 30. The fuel solution 50 after use for power generation does not backflow from a fuel supply section 13, and the fuel solution is not contaminated. Thus the fuel solution 50 used such as commercial beverages can be used for both of drinking and power generation. Also, the fuel solution 50 can be recovered or eliminated only by removing the absorber 30 from the cell 10.

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

PROBLEM TO BE SOLVED: To provide a power supply device capable of simply supplying fuel and generating power in a short time. SOLUTION: The power supply device in which an enzyme is immobilized as a catalyst on at least one electrode of a negative electrode and a positive electrode includes at least an electromotive part in which two or more negative electrodes and positive electrodes are connected in series; a fuel supply part communicating with the negative electrodes and supplying fuel to the negative electrodes; an ion shut off part shutting off ion flow between the negative electrodes. Since the power supply device is formed by connecting two or more electrodes in series, high output current and voltage can be obtained, fuel can be supplied to two or more negative electrodes at the same time, and thereby, fuel can simply be supplied and power can be generated in a short time.

PROBLEM TO BE SOLVED: To easily specify a more efficient enzyme network. SOLUTION: A discharge amount calculation part 164 repeatedly calculate a discharge amount while making an enzyme assignment part 162 change composition ratio of enzyme by control of a repetition control part 167. A maximum value specification part 165 specifies the maximum value of the discharge amount. An unused path deletion part 166 deletes (selects) a path where no enzyme reaction is performed in the enzyme network where the discharge amount becomes maximum. The repetition control part 167 further makes the discharge amount calculation part 164 repeatedly execute calculation of the discharge amount. The present invention is applicable, for example, to a metabolism simulator. COPYRIGHT: (C)2009,JPO&INPIT
