Okino Lab
Machine-translated · View original
A lab that builds new atmospheric-pressure plasma devices and applies them to medicine, analysis, materials, and more.

AboutAbout the lab
Developing atmospheric-pressure plasma devices and applying them in medicine and industry.
The Okino Lab develops new atmospheric-pressure plasma devices and studies their use in a wide range of fields.
It designs and develops diverse plasma devices, from low to high temperature and from small to large, and investigates their properties.
The devices are applied in fields such as medicine, dentistry, analysis, life sciences, materials, the environment, and energy.
The lab carries out its research in collaboration with the university's School of Medicine and School of Dentistry, as well as many universities, research institutes, and companies in Japan and abroad.
Key terms
- Atmospheric-pressure plasma
- Plasma (an electrically charged gas) generated at the same pressure as ordinary air
- Spectroscopic measurement
- A method of splitting light by wavelength (color) and measuring the intensity of each, to investigate the state of whatever emitted the light
- Mass spectrometry
- A method of turning a substance into ions and separating them by mass to determine what it contains and in what amounts

ResearchResearch themes
The Okino Lab develops cutting-edge atmospheric-pressure plasma devices based on plasma engineering, physics, chemistry, electrical engineering, and spectroscopic measurement. Its research covers many fields, including analysis of trace elements in single cells, applications in medicine, dentistry, life sciences, and materials, and decomposition treatment of harmful gases.
*Illustrative imageNew Atmospheric-Pressure Plasma Devices
The lab develops new devices and power supplies, including temperature-controllable multi-gas plasma, supersonic plasma jets, and ultra-compact plasma jets made with metal 3D printers.
*Illustrative imageMeasuring Inside the Plasma
Using spectroscopic measurement, mass spectrometry, and laser-based measurement, the lab investigates the behavior of atoms and molecules inside the plasma. It also simulates heat and gas flow inside the devices.
*Illustrative imageApplications in Medicine, the Environment, and Agriculture
This research uses plasma for analyzing trace elements in single cells such as iPS cells, sterilization and virus inactivation, decomposition of exhaust gas, plant genome editing, hemostasis, and more.
