Non-equilibrium atmospheric microplasmas are a new and fascinating type of a plasma that has tremendous potential in medicine and nanotechnology. Our understanding of the atmospheric microplasmas and the nature of the plasma interaction with biological matter is very limited. In this project, we will, in particular, advance the knowledge of atmospheric microplasmas relevant for medical applications. This research program will serve as a vehicle for undergraduate and graduate education in the field of plasma science. The PIs will make a concerted effort to involve women and under-represented minority students in this project by working closely with the relevant student organizations at George Washington University. To recruit women, the Society of Women Engineers will be contacted and informed of the project activities. In addition, undergraduate students will be engaged in the research through the Work Study program or a Research Experience for Undergraduates supplement. The experience will impart them with the knowledge and the skills to excel in independent academic or industry careers they pursue after completing their education. The educational plan for this project also aims to generate interest in science and technology in the area of plasma science and bioengineering and to reach out to K-12 teachers, school children and their parents. In particular, we plan to interact with local schools in the Metropolitan DC area.The central objective of this project is to understand the underlying physics of non-equilibrium atmospheric microplasmas with a view towards biological applications. To this end we will develop and implement a wide range of new diagnostic methodologies and tools applicable for atmospheric microplasmas. The overall project will address the ionization mechanism, energy balance and conditions for streamer propagation as well as effects related to overvoltage. This project has both fundamental and technological significance. The fundamental significance of this project is in understanding the underlying physics of non-equilibrium atmospheric microplasmas. To this end a wide spectrum of diagnostic instrumentation for atmospheric pressure microplasmas will be developed. Availability of this instrumentation has critical importance for the future progress of the field of atmospheric microplasmas. Enabled by these advances, the technological significance lies in exploring the wide range of applications of atmospheric microplasmas, such as plasma medicine and nanotechnology.

非平衡大气微等离子体是一种新型且令人着迷的等离子体，在医学和纳米技术方面具有巨大的潜力。我们对大气微等离子体以及等离子体与生物物质相互作用的性质的了解非常有限。在这个项目中，我们将特别推进与医学应用相关的大气微等离子体的知识。该研究计划将作为等离子体科学领域本科生和研究生教育的载体。 PI 将与乔治华盛顿大学的相关学生组织密切合作，共同努力让女性和代表性不足的少数族裔学生参与该项目。为了招募女性，将联系女工程师协会并告知项目活动。此外，本科生将通过勤工俭学计划或本科生研究经验补充项目参与研究。这些经验将为他们传授知识和技能，使他们在完成学业后能够在独立的学术或行业职业中脱颖而出。该项目的教育计划还旨在激发人们对等离子体科学和生物工程领域的科学技术的兴趣，并接触到 K-12 教师、学童及其家长。特别是，我们计划与华盛顿特区的当地学校进行互动。该项目的中心目标是了解非平衡大气微等离子体的基本物理原理，以期实现生物应用。为此，我们将开发和实施一系列适用于大气微等离子体的新诊断方法和工具。整个项目将解决电离机制、能量平衡和流光传播条件以及与过电压相关的影响。该项目具有基础意义和技术意义。该项目的根本意义在于了解非平衡大气微等离子体的基本物理原理。为此，将开发用于大气压微等离子体的广泛诊断仪器。该仪器的可用性对于大气微等离子体领域的未来进展至关重要。这些进步的技术意义在于探索大气微等离子体的广泛应用，例如等离子体医学和纳米技术。
