This article contextualizes how the antimicrobial properties and antipathogenic contact killing/inactivating performance of copper cold spray surfaces and coatings and can be extended to the COVID-19 pandemic as a preventative measure. Specifically, literature is reviewed in terms of how copper cold spray coatings can be applied to high-touch surfaces in biomedical as well as healthcare settings to prevent fomite transmission of SARS-CoV-2 through rapidly inactivating SARS-CoV-2 virions after contaminating a surface. The relevant literature on copper-based antipathogenic coatings and surfaces are then detailed. Particular attention is then given to the unique microstructurally-mediated pathway of copper ion diffusion associated with copper cold spray coatings that enable fomite inactivation.
本文阐述了铜冷喷涂表面及涂层的抗菌特性和抗病原体接触杀灭/灭活性能,以及如何将其作为一种预防措施应用于新冠疫情。具体而言,本文回顾了相关文献,探讨了铜冷喷涂涂层如何应用于生物医学和医疗环境中的高接触表面,以通过在污染表面后迅速灭活新冠病毒粒子来防止新冠病毒的 fomite 传播。随后详细介绍了有关铜基抗病原体涂层和表面的相关文献。接着特别关注了与铜冷喷涂涂层相关的独特的微观结构介导的铜离子扩散途径,该途径能够实现 fomite 灭活。
