当被大气等离子体射流照射时，目标表面上的活性氧物种（ROS）的分布模式需要被理解，特别是对于生物医学应用。在本文中，KI-淀粉琼脂被用来可视化的ROS的分布，并将结果与灭菌模式的酵母，这是用来评估等离子体处理，通常培养在琼脂上进行比较。因为琼脂表面可以受到来自等离子体射流的气流的影响，所以在开启等离子体之前的气体暴露时间是变化的，并且在KI-淀粉琼脂上观察到其对ROS分布的影响。结果发现，等离子体照射前的气体暴露时间的影响的KI-淀粉琼脂上的活性氧的分布模式。通过细颗粒可视化实验进一步探讨了图案形成的机理。
The distribution patterns of reactive oxygen species (ROS) on a target surface when irradiated by an atmospheric plasma jet need to be understood, especially for biomedical applications. In this paper, a KI-starch agar was used to visualize the distribution of ROS, and the results were compared with sterilization patterns for yeast, which are used to evaluate plasma treatments and are commonly cultivated on agar. Because the agar surface can be affected by gas flow from the plasma jet, the gas exposure time before turning on the plasma was varied and its effects on ROS distribution were observed on the KI-starch agar. It was found that the gas exposure time before plasma irradiation influenced the distribution patterns of the ROS on the KI-starch agar. The mechanism for the pattern formation was explored further via a fine particle visualization experiment.
