On February 17, 2021, a study session on Department of Frontier Photonic Sciences was held online by the National Institutes of Natural Sciences Center for Novel Science Initiatives (CNSI)

Department of Frontier Photonic Sciences, we hold study sessions with the aim of touching on cutting-edge topics that are different from existing spectroscopy, optical properties, and imaging, and triggering the acquisition of new research ideas that transcend fields. ..

In this study group, researchers of four advanced optical field, Yuichi Ozawa Associate Professor (Tohoku University Institute of Multidisciplinary Research for Advanced Materials), Tanaka, Takuo Senior Researcher (RIKEN Tanaka metamaterial laboratory), Tomoko Inose specific Assistant Professor (Kyoto University of material - cell integrated system base), Hiroshi Yukawa Project Associate Professor (Nagoya University nano-Life Research Institute) has been lecture.

Yuichi Ozawa Associate Professor has been talk about the properties of light and optical imaging application that has a spatial structure.
This is a new microimaging that realizes unprecedented spatiotemporal resolution and depth of field by utilizing the characteristic properties of light propagating while having a spatiotemporal structure that goes beyond classical electromagnetism. It strongly suggested the realization of the above and its application to life science.

Senior Researcher Takuo Tanaka gave a lecture on metamaterial absorbers and high-sensitivity spectroscopic technology.
Metamaterials create unique optical characteristics that cannot normally be obtained, such as negative refractive index, by designing and artificially creating structures smaller than the wavelength of light. It was explained. Increasing the sensitivity of infrared absorption spectroscopy using metamaterials is one of its applications, and the results of actually experimentally increasing the sensitivity were introduced, and the lecture showed a part of the wide applicability of metamaterials.

Assistant Professor Tomoko Inose gave a lecture on local spectroscopy technology using plasmon waveguide nanolight source.
Viable intracellular Department by the development of insertable nano search needle, viable intracellular Department was obtained by realizing the spectroscopic measurement of high sensitivity in the super local region. This technology was epoch-making in that it opened the way from basic life sciences such as the effects of anticancer drugs and cancer research to medical applications.

Hiroshi Yukawa Project Associate Professor has been talk on biomedical applications of cutting-edge imaging measurement techniques based on quantum nano-optics.
Currently, the life science application of quantum measurement technology is an interdisciplinary research field that is receiving a great deal of attention from both inside and outside the country. In particular, future applications such as cadmium-free new quantum dots and intracellular local temperature measurement using nitrogen lattice-deficient fluorescent nanodiamonds were expected.



62 researchers and students from domestic universities and companies participated in this study session, which was a valuable opportunity to learn about cutting-edge research content.
It was also sponsored by the Advanced Bioimaging Support Platform (ABiS).
