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.********

拟议研究的结果应有助于减少表面细菌存活的努力。虽然表面上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。有很多报道说，加拿大每年至少有20万患者在医疗机构感染，估计有8,000人死于这些感染。人们常说，大多数常见感染是由医护人员、病人和访客传播的，适当的手部卫生可以显著降低感染率。报警统计，例如，艰难梭菌相关的死亡率在过去二十年中增加了两倍多，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1,000%以上，这表明除了那些传统的目标之外，还应该解决其他因素。我们假设，流行的微生物群落（微生物组）是特定于场所的;重症监护病房中的微生物组是导致重症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组可能是短暂的，并受到季节的影响。瑞尔森的团队专注于使表面抗菌的方法，而行业合作伙伴开发了一种有前途的技术，涉及嵌入抗菌剂的透明屏幕保护器，并需要瑞尔森的专业知识在现实条件下演示该技术。触摸屏成为通信和信息管理的主要形式-食品加工厂，餐厅菜单和医疗保健环境是几个例子。为了获得足够的样本以进行统计上合理的评估，我们将与Mt.西奈医院测试移动的手机上的技术，由于他们在医疗环境中的流行。在这种环境下的演示也将为触摸屏成为信息传输规范的其他环境中的技术提供信心。
