尊敬的编辑：中国武汉报告称，严重急性呼吸综合征冠状病毒2（SARS-CoV-2）在医院病房的空气和物体表面广泛分布，这表明医务人员和其他密切接触者存在医院感染的潜在风险。[1]在另一份报告中，货车Doremalen等人[2]表明，尽管SARS-CoV-2在塑料和不锈钢上稳定存活长达72小时，但在铜上4小时后仍无法检测到。他们的研究结果表明，某些金属，如铜，可以成为一种抗病毒材料，以防止环境污染的SARS-CoV-2。我们最近开发了一种新的透明铜膜使用溅射方法（申请专利;合作研究与UACJ公司，东京，日本）。根据国际标准化组织（ISO）规则（可在ISO网站3上在线获得），我们证明了这种新薄膜对金黄色葡萄球菌和大肠杆菌的抗菌效果。本研究中使用的菌株
Dear Editor, The wide distribution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the air and object surfaces in hospital wards, which indicates a potential risk of nosocomial infection for medical staff and other close contacts, was reported from Wuhan, China. 1 In another report, van Doremalen et al. 2 showed that SARS-CoV-2 was not detectable on copper after 4 h, although it was stable and viable on plastic and stainless steel up to 72 h. Their results indicated that some metals, such as copper, could become an antiviral material to protect against environmental contamination from SARS-CoV-2.We recently developed a novel transparent copper film using a spattering method (patent applied for; cooperative research with UACJ Corporation, Tokyo, Japan). According to the International Organization for Standardization (ISO) rules (available on line at the ISO website3), we proved the antibacterial effect of this new film against Staphylococcus aureus and Escherichia coli. The strains used in this study
