Recent advancements in photochemistry and spectroscopy related to biology

DATE

TITLE

「Recent advancements in photochemistry and spectroscopy related to biology」

ORGANIZER

Shigekazu Kumazaki (Kyoto University)

PURPOSE

There are many biological phenomena in which photochemistry and photophysics are deeply relevant. Well known examples are photosynthesis, light-sensing, photo-induced damages and protection against such damages etc. Some of them are remarkably efficient and realized by a fine-tuned structure at a molecular level based on natural chromophores and surrounding proteins. They have been a textbook for synthesis-oriented photochemist to mimic the photochemical functions. They have also been a test-bed for manipulating the natural photochemical reaction into more convenient reactions for human society.

Biological photochemical reaction is not the only overlap between biology and photochemistry. Nowadays, many microscopic techniques, especially laser scanning confocal fluorescence microscopy, are indispensable tools for molecular biology to sense expression, localization, diffusion, and interactions of biological molecules. Tremendous progress has been made in various aspects of optical microscopy in recent years (superresolution, parallel image acquisition, many spectroscopic methods to be integrated in microscopy) and many of them are extensively used for a wide range of medical applications and biological studies. Such microscopic techniques are naturally useful for studies on photochemistry at interfaces and heterogeneous structures. Not only fluorescent molecules but also non-fluorescent molecules can be studied by vibration-sensitive optical spectroscopy including Raman scattering and infrared absorption spectroscopy with different selection rules. This simple physicochemical principle is now widely used in analysis of cells and proteins.

Given the above background, this symposium is planned to stimulate an interdisciplinary discussion between photochemistry, spectroscopy and biology. New spectroscopic and microscopic techniques applicable to single photosynthetic molecules, membrane proteins, cells and macroscopic objects will be introduced through studies on suitable biological problems.
