- Attempt to sterilize the surface of deep space probe by oxygen plasma.
Ultimately, we aim to be registered as a space probe sterilization method at COSPAR (International Committee for Space Research). - Seeds irradiated with oxygen plasma promote germination and growth.
In order to elucidate the mechanism of germination and growth promotion, how seeds irradiated with oxygen plasma receive active oxygen and
The purpose is to clarify whether the active oxygen signal is transmitted to the inside of the seed.
To analyze the surface of oxygen-plasma-irradiated seeds, TOF-SIMS is used to examine changes in surface molecules. - Mass synthesis of silver nanoparticles (Ag NPs) is performed by discharge plasma to generate Ag NPs hydrogel.
The generated hydrogel is used to sterilize seeds and soil to promote seed germination and growth. - By irradiating the seeds of Angelica acutiloba, which is a medicinal plant, with oxygen plasma, germination and growth were promoted, root yield was increased, and medicinal ingredients were increased.
- To confirm that a chemical-free, zero-emission, high-velocity low-temperature plasma sterilizer that is completely harmless to humans and the environment can be used in spacecraft and confined spaces that are difficult to ventilate, and to determine the optimal operating parameters. Do research. In particular, we clarify the sterilization evaluation and material compatibility when using water plasma. 1. Material suitability: The low-pressure oxygen plasma sterilization method is applied to the sterilization and protein removal of medical equipment and various parts actually used in spacecraft, and the adaptability of this sterilization method to various equipment and parts. reveal gender. 2. Sterilization of the surface of the space probe: Attempt to sterilize the surface of the space probe, and at the same time confirm the suitability of the material. Optimize the water plasma source.
- Agricultural and medical application research of plasma will be conducted at Kobayashi Laboratory of Chulalongkorn University, Thailand.
- Sterilize the bacteria attached inside the Itoshima oyster with ozone water.

- Atmospheric pressure helium torch plasma was used to efficiently induce apoptosis in oral cancer cells, contributing to the practical application of plasma-based cancer treatment.
- By irradiating oral cancer cells with atmospheric pressure helium plasma, we succeeded in capturing the induction of apoptosis as a time-lapse movie.
- By using atmospheric pressure air plasma, we succeeded for the first time in the world in sterilizing the inner surface of a catheter of about 1 m, which had not been realized so far.
