Outline of Final Research Achievements

We investigated synergistic functions of hybrid materials consisting of inorganic layered semiconductors and biomolecules. It was revealed that redox enzymes as biomolecules are intercalated into interlayer space of layered semiconductors with a narrow band gap, then enzymatic activity can be manipulated by visible light irradiation to the hybrids. On the other hand, binding of photoproteins to semiconductors achieved excitation of the semiconductor with bioluminescence, implying that photoproteins can be employed as an internal light source for semiconductor photocatalytic reaction systems without any external one.
