Assistant Professor Mime Kobayashi received the 40th JSAP (The Japan Society of Applied Physics) Outstanding Paper Award.

Assistant Professor Mime Kobayashi of the Information Device Science Laboratory has been awarded one of the 40th JSAP (The Japan Society of Applied Physics) Outstanding Paper Awards. The award ceremony was held in Nagoya on September 18, 2018 during the 79th JSAP Autumn Meeting.

JSAP has more than 20,000 members and the Award is presented to the authors of outstanding papers published in the Japanese Journal of Applied Physics (JJAP) and Applied Physics Express (APEX) in the past 2 years. Out of 3400 papers, 41 were nominated and 7 were awarded. Award papers are free to download for a limited period. The paper was co-authored with researchers from Toyota Technological Institute and terraplasma (Germany).

As a molecular biologist, I am honored to be recognized by Japan Society of Applied Physics that has a long tradition of nurturing excellent research achievements in applied physics. I am grateful for support provided by NAIST to pursue challenging interdisciplinary research topics. After graduating with a Ph.D. from NAIST, I spent years studying different disciplines in other institutions including Cornell and NTT Basic Research Laboratories. Everything I learned and experienced throughout my carrier culminated in this work. Our research has inspired many scientists around the world as indicated by nearly 3000 downloads of the paper since its publication. At NAIST, we have already started collaboration projects with researchers in the Divisions of Materials Science and Biological Science. I hope that our research eventually leads to help building a better society for human beings.

Cold (non-thermal) atmospheric pressure plasma generates active species such as radicals, ions, and electrons. Plasma irradiation has been used to heal skin wounds, and application for cancer treatment has been reported. However, the mechanism of plasma effects has not been well understood because of physical and chemical complexity of plasma. Dr. Kobayashi, along with Prof. Kumagai (Now at Meijo Univ.) and other collaborators, developed a new device which can be used to analyze the effects of plasma in a single cell. We have already published a paper reporting a method for gene expression analysis upon plasma irradiation. Close collaboration of researchers with different scientific backgrounds has been essential to achieve the goal. Application of plasma in biological sciences will be one of the hot topics in the near future.
