Abstract An investigation of the treatment effect of atmospheric cold plasma (ACP)-generated reactive oxygen species (ROS) against problematic bacteria of chronic wounds is presented. To study ROS effects specifically, a vacuum chamber with a flowmeter to control the background gas composition and a mesh electrode for a dielectric barrier discharge (DBD) device were used. In addition, a numerical modeling was developed to simulate the amount of ROS flux transported from the mesh electrode to determine which of the ROS species was the main factor in the treatment effect. Considering the experimental and computational results and the effective transport distance of each species, ozone could be the main factor in the experimental results.

来自生物膜形成细菌的介质阻挡放电装置的间接大气等离子体的可用性

摘要介绍了大气冷等离子体 (ACP) 产生的活性氧 (ROS) 对慢性伤口问题细菌的治疗效果的研究。为了专门研究 ROS 效应，使用了带有流量计的真空室来控制背景气体成分，并使用用于介质阻挡放电 (DBD) 设备的网状电极。此外，还开发了一个数值模型来模拟从网状电极传输的 ROS 通量，以确定哪种 ROS 物种是治疗效果的主要因素。考虑到实验和计算结果以及每个物种的有效传输距离，臭氧可能是实验结果的主要因素。
