文档名:等离子体活化介质技术及其生物医学应用
摘要:等离子体生物医学兴起20余年来,已有多项技术通过美国食品药品监督管理局(FDA)认证并推广应用,但现有的应用方式主要采用等离子体直接处理生命体,存在处理面积小、作用深度浅、有效时间短、稳定性不足等问题,限制了等离子体生物医学的适用范围和应用效果.为此,在近10年研究基础上,发展了等离子体活化介质技术,即:采用等离子体活化处理气体、液体或水凝胶等介质材料,将活性粒子加载到介质材料中再应用,使等离子体生物医学从直接处理变革到间接处理,推动实现"更大面积、更深部位、安全稳定、持续有效"的应用升级.该文总结了等离子体活化介质技术的形成背景与研究现状,分析该技术当前面临的关键科学和技术问题,给出最新研究结果并展望未来发展方向,以期为同行学者和研究生提供参考.
