Outline of Final Research Achievements

In-situ observation techniques of morphological changes of biomaterials under plasma exposure were investigated in this study. For example, a catheter-type compact plasma source, which can be installed to “wet SEM capsule”, was developed, and plasma discharge characteristics in atmosphere and liquid, and active species measurements were conducted. In addition, gas supply and pressure control system, and circulatory flow system of liquid were also studied. On the other hand, morphological changes of plasmid DNA under an exposure of plasma-activated medium (PAM) was observed by a high-speed scan in-liquid atomic force microscope. Active species in the PAM were also evaluated and measured.
