Antimicrobial touch screen**

拟议的研究成果应有助于减少细菌在表面的生存。虽然表面的腐败和致病菌的持续存在在许多环境中构成了挑战，但该项目的重点将是对人类健康构成显著威胁的触摸屏。有很多关于这样一个事实的报道，即每年至少有20万名患者在加拿大的医疗机构中感染，估计有8000人死于这些感染。人们经常说，大多数常见的感染是由医护人员、病人和来访者传播的，适当的手部卫生可以显著降低感染率。例如，与艰难梭菌相关的死亡率在过去20年中增加了两倍以上，与医疗保健相关的耐甲氧西林金黄色葡萄球菌感染率增加了1000%以上，这些令人震惊的统计数据表明，除了那些通常被作为目标的因素之外，还应该解决其他因素。我们假设，流行的微生物群落(微生物群落)是特定地点的；重症监护病房的微生物群落是导致危重患者医院感染的耐药微生物的储存库，而公共场所的微生物群落可能是短暂的，受季节的影响。Ryerson的团队专注于表面抗菌处理的方法，而该行业合作伙伴开发了一项前景看好的技术，该技术涉及嵌入抗菌剂的透明屏幕保护器，需要Ryerson的专业知识在现实条件下演示这项技术。触摸屏成为沟通和信息管理的一种主要形式，食品加工厂、餐厅菜单和医疗保健环境就是其中的几个例子。为了获得足够的样本，以便进行统计上合理的评估，我们将与Mt.由于手机在医疗保健环境中的普及程度，西奈医院将在手机上测试这项技术。在此背景下的演示还将在触摸屏成为信息传输标准的其他环境中提供对该技术的信心。

The outcome of the proposed research should make a contribution to efforts aimed at reducing the survival of bacteria on surfaces. While the persistence of spoilage and pathogenic bacteria on surfaces poses challenges in numerous environments, the focus of this project will be on touch screens that pose a notable threat to human health. There is much coverage of fact that at least 200,000 patients get infections per year while in healthcare facilities in Canada, with an estimated 8,000 who die due to these infections. It is often stated that the majority of common infections are spread by healthcare workers, patients and visitors, and that proper hand hygiene can significantly reduce infection rates. Alarming statistics of e.g., Clostridium difficile related mortalities that have more than tripled over the last two decades, and healthcare-associated methicillin-resistant Staphylococcus aureus infection rates that increased by more than 1,000%, suggest that factors in addition to those conventionally being targeted should be addressed. We hypothesize that prevalent microbial communities (microbiomes) are site-specific; the microbiome in intensive care units serves as reservoir of resistant microorganisms causing nosocomial infections in critically ill patients, while those of public spaces may be transient and influenced by i.e. the season. The group at Ryerson focuses on approaches to render surfaces antimicrobial, while the industry partner developed a promising technology that involves a transparent screen protector embedded with an antimicrobial agent, and needs Ryerson's expertise to demonstrate the technology under real-world conditions. Touchscreens became a major form of communication and information management - with food processing plants, restaurant menus, and the healthcare environment being a few examples. In order to obtain sufficient samples to allow statistically sound evaluation, we will coordinate with Mt. Sinai hospital to test the technology on mobile phones due to their prevalence in the healthcare environment. Demonstration in this setting will also provide confidence in the technology in other environments where touch-screens became the norm of information transfer.********
