Prof. Osamu Niwa, Saitama Industrial University, Japan, and Yuko Ueno, Researcher, Nippon Telegraph and Telephone Corporation, visited our institute for academic exchange

At the invitation of Professor TianYan You from our School, Professor Osamu Niwa from Saitama Polytechnic University and researcher Yuko Ueno from Nippon Telegraph and Telephone Corporation came to our school for short-term interviews and academic exchanges from August 15 to August 17, 2017.

Osamu Niwa graduated from Department of Applied Chemistry, Kyushu University, Japan, in 1990 with a Ph.D. He is currently a professor at Saitama Industrial University in Japan and a part-time professor in the Department of Electronic Chemistry at the Graduate School of Science and Engineering at Tokyo Institute of Technology. Former Japan Institute of Industrial Technology (AIST) Materials Science and Engineering, Nippon Telegraph and Telephone Company (NTT) Environmental Technology Research Institute. His research interests include novel nanoscale carbon film biosensing and electro- analytical applications, electrochemical biosensors, micro / nano-electrode sensing devices, surface plasmon resonance (SPR) devices, and microfluidic devices for biomedical and clinical testing and nano- and Soft biological interface and other aspects of the application. He has published more than 200 papers on SCI and has published over 200 high-level papers on SCI with a total quotation of 4,700 times and a H-index of 36.

Yuko Ueno, graduated from the Faculty of Chemistry, The University of Tokyo, Japan, in 2002 with a Ph.D. 2004 - 2005 at the University of California, Berkeley, Lawrence Berkeley National Laboratory postdoctoral research. The current NTT, basic research institute, senior researcher. His research interests include the control of biomolecule interfaces on solid surfaces and their applications in biosensors. The ultra-low frequency vibration mode studies the non-covalent interactions in organic crystals. Won the Japan Society of Analytical Chemistry Young Fellow Award.

August 16, 9: 00-11: 00 In the conference room 201 of the College of Agricultural Equipment Engineering, Professor Osamu Niwa and researcher Yuko Ueno made speeches entitled "Nanoparticles and nanoalloy embedded carbon film electrodes for electroanalysis" respectively for professors and postgraduates in our institute. "Graphene FRET aptasensor built on a solid support" of the school academic report. Prof. Osamu Niwa introduced the research results of its R & D team on the preparation and application of metal nanoparticle supported carbon film electrode and the latest research progress in the field of this field internationally. Metal nanoparticle (NPs) modified electrodes are widely used in fuel cells, chemical sensors and electro- analytic fields. However, the interaction between the metal nanoparticles and the electrode surface is weak, so that the nanoparticles are easily detached from the electron surface. By co-sputtering metals and carbon precursors, Professor Osamu Niwa's team developed a variety of carbon-supported carbon-based electrodes for metal nanoparticles. In this structure, since the metal nanoparticles are firmly embedded in the carbon film, the detachment of the nanoparticles is greatly suppressed. And Yuko Ueno researcher mainly introduced the research status of graphene composite-based fluorescence resonance energy transfer sensor. She described the physicochemical properties of graphene and its oxides in detail, and introduced the mechanism of fluorescence resonance energy transfer and its research status. Based on the distance dependence of the fluorescence resonance energy transfer efficiency on the dye and quencher, they designed a novel fluorescent probe for the highly sensitive detection of proteins in graphene oxide aptamer sensors.

A number of teachers from the School of Agricultural Equipment Engineering, School of Chemistry and Chemical Engineering and Food Science attended the academic report. Professor Mao Hanping of Agricultural Equipment Engineering College presided over this report. The participating teachers and students conducted extensive and in-depth academic exchanges and discussions with Professor Osamu Niwa and researcher Yuko Ueno. This report has expanded the international vision of young teachers and students in the college and gained an understanding of the latest trends in related fields. This exchange of visits laid a good foundation for further research.
