Outline of Final Research Achievements |
Reactive oxygen species are generated by atmospheric pressure plasmas. Especially, OH radical is significant for many reactions. We have developed a detection method of OH radicals. The method is based on the trapping of OH radicals in liquid by terephthalic acid (TA) and its product, 2-hydroxyterephthalic acid (HTA), can be detected by fluorescence measurement. However, as HTA molecules diffuse in liquid, we could not obtain the information of OH radical distribution for the radical source. To overcome this difficulty, we developed a smart hydrogel, which consists of TA content water in agarose. The OH radical generation in dielectric barrier discharge, plasma jet, and pulsed streamer corona was examined. The two-dimensional visualization of OH radicals was successful performed. The gel sheet has a wearable function and it can be attached onto various materials. Therefore, we can estimate the area of OH radical supply for the target such as a skin surface and plant leaf.
