　Photochemistry is closely related to many fields, including biological phenomena such as photosynthesis and sunburn, medical fields such as photodiagnosis and phototherapy, and device fields such as solar cells and organic EL. In our laboratory, we are conducting research to visualize (imaging) various biological information in living cells and tissues by observing molecular luminescence phenomena under a microscope. We are one of the few laboratories in Japan that can synthesize luminescent molecules, evaluate their photophysical properties, and conduct a series of cell and mouse experiments. It is very impressive to see my molecules glowing in the cell, and the light conveys various messages to researchers all over the world (Seeing is believing!).

　About 25 years have passed since it was said that the 21st century is the “age of light. Our daily lives are filled with many products that utilize light. Light is also actively used in the life sciences. Chemistry, which produces matter, can be used in a variety of fields, including biology, medicine, pharmacy, the food industry, and materials development. Let’s work together to develop a new My Molecule that will be used in the world of biology, medicine, and pharmaceuticals, while tackling the fascinating theme of the application of light to the life sciences.

　Students assigned to our laboratory have a study session on photochemistry once a week to acquire basic knowledge for their graduation research. The unique feature of our laboratory is that students can conduct molecular design and synthesis, photochemical measurements, cellular experiments, and small animal experiments in a single series. In addition, “photochemical measurement” is performed in all research themes. This allows students to develop not only as researchers in photochemistry, but also to acquire a wide range of knowledge and skills in chemistry and biology. Of course, it takes a lot of effort to conduct a wide range of research. It also takes time. Students who wish to be assigned to our laboratory should consider continuing on to a master’s or doctoral degree. Many PhDs have graduated from our laboratory so far and are active in companies, universities, and research institutes. We are committed to helping you grow as researchers, so please come visit our laboratory if you are interested.
