Understanding and construction of plasma induced reaction field in liquid for plasma bio processes

为了了解低温常压等离子体与生物体的反应过程，研究了活性物种与生物大分子之间的反应。由于人体处于潮湿状态，液体中产生的活性物质很重要，因此对液体中的活性物质进行了测定。观察血浆对引起阿尔茨海默病的氨基酸、蛋白质、血脂和淀粉样β蛋白的影响。使用含有染料的胶束评估细胞内的氧化应激。证实了降低pH值的方法增加了氧化应激的增量。

For understanding the reaction processes of low temperature atmospheric pressure plasma to living organism, the research of the reaction between active species and biomacromolecule. As human body is wet condition and active species generated in liquid are important, measuremants of active species in liquid were done. Effects of plasma to amino acid, protein, lipid were evaluated and amyloid beta protein, which cause Alzheimer disease. intracellular oxidation stresses were evaluated using dye included micelle. It was confirmed that increment of oxidative stress was increased with the reduced pH methods.
