In the first embodiment, the polymer membrane 3 is made of polyvinyl chloride (PVC), dioctyl adipate (DOA), and plant tissue extracted from spinach with tetrahydrofuran, and a gold electrode is formed on the polymer membrane to form an ITO film. A voltage was applied between the electrode and the gold electrode, and the current was measured. A in the figure
Curve is a result measured in a dark state, that is, a state where light is blocked, and b is a result measured in a bright state, that is, under a light irradiation condition. As a result, the current value under light irradiation is about two orders of magnitude larger than the current value in the dark state, and the current can be taken out under light irradiation even when no voltage is applied. That is, it can be used as a solar cell. This is because the chlorophyll in the plant tissue extracted from spinach cooperates with other biological substances to efficiently perform photosynthesis under light irradiation.

A silver-silver chloride electrode 7 was formed on a water-resistant insulating substrate 6, and a polymer film 3 in which a plant tissue or an extract obtained from a plant tissue was dispersed or dissolved was laminated on the silver-silver chloride electrode. . As another conductive electrode, a reference electrode 8 composed of a silver-silver chloride electrode or a calomel electrode was arranged via an aqueous solution. In this example, when the ion concentration in the aqueous solution changes,
An electromotive force corresponding to the ion concentration is generated in the polymer film, and this electromotive force is measured as a potential change between the silver-silver chloride electrode and the reference electrode. If you calibrate the potential with a solution of known concentration in advance,
The ion concentration can be known by measuring the potential change. That is, an ion sensor can be manufactured.
In this example, the property that the cell membrane of the plant selectively permeates only a specific ion and a large concentration difference is generated between the inside and outside of the cell to generate the cell membrane potential is used. A part of the cell membrane tissue dispersed in the polymer membrane exists on the polymer membrane surface, and a specific ion in a solution in contact with the polymer membrane is selectively taken into the polymer membrane to reach equilibrium. Electromotive force is generated in the film because the charged ions move from the aqueous solution phase to the film phase.
