The broader impacts of this RAPID project will provide an effective means to control and manage the spread of coronavirus disease (COVID-19) originating from non-biological objects. This effort will lead to rapid development and testing of a new technology to be used against coronaviruses. The current COVID-19 pandemic has generated worldwide awareness for the need to decontaminate the environment and to reduce the risk of transmission of the virus. As SARS-CoV-2 (the virus that causes COVID-19) was newly introduced into the human realm, uncertainty remains regarding the virus's spread and ways of decontamination. It has been reported that coronaviruses might survive over three days on common materials such as plastics, ceramics, glass and stainless steel. Cleaning and disinfection of environmental surfaces are important for infection prevention and control of healthcare-associated infections. This includes requirements for surface disinfection, airborne virus decontamination and skin decontamination. The proposed RAPID project will advance the development of Cold Adaptive Atmospheric Plasma Decontamination as an efficient approach for disinfection. The project will develop a disinfection system based on cold adaptive atmospheric plasma (CA2P), in combination with rapid detection of the contamination on these surfaces. The proposed concept is an adaptive non-thermal plasma system. This plasma-based system will be capable of rapidly scanning for viral colonies on the surface and simultaneously directing the CA2P beam for viral kill. The system will also be tested for treatment of airborne viruses. Compared to current disinfection methods based on wet chemistry (biocidal chemicals), the proposed CA2P technique would not cause corrosion of materials nor create toxic chemicals.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个快速项目的更广泛的影响将提供一种有效的手段来控制和管理源自非生物学对象的冠状病毒疾病（Covid-19）。 这项工作将导致对冠状病毒使用的新技术的快速开发和测试。 目前的Covid-19大流行已经引起了全世界的意识，因为有必要净化环境并降低病毒传播的风险。 由于SARS-COV-2（导致Covid-19的病毒）新引入人类领域，因此病毒的扩散和净化方式仍然存在不确定性。 据报道，冠状病毒可能在三天内生存在塑料，陶瓷，玻璃和不锈钢等常见材料上。 环境表面的清洁和消毒对于预防感染和控制医疗相关感染非常重要。 这包括表面消毒，空气传播病毒去污和皮肤去污的要求。提出的快速项目将推动冷自适应大气等离子体净化的发展，作为一种有效的消毒方法。该项目将基于冷自适应大气等离子体（CA2P）开发一种消毒系统，并结合对这些表面上污染的快速检测。 提出的概念是一种自适应的非热等离子体系统。该基于等离子体的系统将能够快速扫描表面上的病毒菌落，并同时指导CA2P梁以进行病毒杀伤。 该系统还将进行测试以治疗空气传播病毒。 与基于湿化学（杀生物化学物质）的当前消毒方法相比，提出的CA2P技术不会引起材料的腐蚀或产生有毒化学物质的腐蚀。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
