摘要

聚乙烯醇-碘化钾(PVA-KI)溶液作为辐射剂量计已被提出，因为它在活性自由基的存在下显示出明显的颜色变化。本研究利用PVA-KI可视化了大气压等离子体射流与溶液相互作用过程中自由基的产生和输运。首先，我们关注在不同温度下存储PVA-KI样品溶液的挑战。PVA-KI显色反应的重现性取决于此条件。此外，还对自由基的产生机理和自由基类型进行了初步研究。

Reactive radical study using the polyvinyl alcohol–potassium iodide solution as a new chemical probe

: Polyvinyl alcohol–potassium iodine (PVA-KI) solution as a radiation dose meter has been proposed because it shows clear color changes in the presence of reactive radicals. Here, PVA-KI is studied to visualize the production and transport of radicals during the interaction between the atmospheric pressure plasma jet and the solution. First, we focus on the challenges of storing the PVA-KI sample solution at different temperatures. The reproducibility of the PVA-KI color reaction depends on this condition. Additionally, preliminary findings on the radical produc tion mechanism and radical types are provided.

期刊介绍： Technology has always played an important role in medicine and there are many journals today devoted to medical applications of ionizing radiation, lasers, ultrasound, magnetic resonance and others. Plasma technology is a relative newcomer to the field of medicine. Experimental work conducted at several major universities, research centers and companies around the world over the recent decade demonstrates that plasma can be used in variety of medical applications. It is already widely used surgeries and endoscopic procedures. It has been shown to control properties of cellular and tissue matrices, including biocompatibility of various substrates. Non-thermal plasma has been demonstrated to deactivate dangerous pathogens and to stop bleeding without damaging healthy tissue. It can be used to promote wound healing and to treat cancer. Understanding of various mechanisms by which plasma can interact with living systems, including effects of reactive oxygen species, reactive nitrogen species and charges, has begun to emerge recently. The aim of the Plasma Medicine journal will be to provide a forum where the above topics as well as topics closely related to them can be presented and discussed. Existing journals on plasma science and technology are aimed for audiences with primarily engineering and science background. The field of Plasma Medicine, on the other hand, is highly interdisciplinary. Some of prospective readers and contributors of the Plasma Medicine journal are expected to have background in medicine and biology. Others might be more familiar with plasma science. The goal of the proposed Plasma Medicine journal is to bridge the gap between audiences with such different backgrounds, without sacrificing the quality of the papers be their emphasis on medicine, biology or plasma science and technology.
