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.

该 RAPID 项目的更广泛影响将为控制和管理源自非生物物体的冠状病毒疾病 (COVID-19) 的传播提供有效的手段。 这项努力将导致快速开发和测试用于对抗冠状病毒的新技术。 当前的 COVID-19 大流行使全世界意识到需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）刚刚被引入人类领域，该病毒的传播和净化方法仍然存在不确定性。 据报道，冠状病毒可以在塑料、陶瓷、玻璃和不锈钢等常见材料上存活超过三天。 环境表面的清洁和消毒对于预防和控制医疗相关感染非常重要。 这包括表面消毒、空气传播病毒净化和皮肤净化的要求。拟议的 RAPID 项目将推动冷适应性大气等离子体净化作为一种​​有效消毒方法的发展。该项目将开发一种基于冷适应性大气等离子体（CA2P）的消毒系统，并结合快速检测这些表面上的污染物。 所提出的概念是自适应非热等离子体系统。这种基于等离子体的系统将能够快速扫描表面上的病毒菌落，同时引导 CA2P 光束杀死病毒。 该系统还将针对空气传播病毒的治疗进行测试。 与目前基于湿化学（生物杀灭化学品）的消毒方法相比，所提出的 CA2P 技术不会导致材料腐蚀，也不会产生有毒化学物质。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和评估进行评估，被认为值得支持。更广泛的影响审查标准。
