Inherently anti-viral surfaces: protecting Canadians with field-deployable antiviral coatings

随着加拿大人重返工作岗位，SARS-CoV-2仍将对他们构成威胁。虽然检测、隔离、治疗和接触者追踪是必不可少的，但我们也希望尽量减少通过接触公共表面在人与人之间传播病毒的风险。该项目由温莎大学和安大略涂料公司Tessonics牵头，结合了三种不同的策略来开发一种持久的抗病毒涂层，这种涂层可以应用于表面，并可以在接触时破坏病毒粒子。它对人类接触是安全的，不粘，摸起来很舒服。它可以应用于公共建筑（医院、警察或消防部门、职业介绍所）和基本零售（杂货店、药店、加油站）的门把手、加油站的把手、支付系统的键盘、电梯按钮、电气开关和其他难以持续消毒且经常被大量人员接触的表面。这在机场和大型公用事业公司等公共共享空间尤其有用。我们的目标是使用超高沸点液体或基于它们的聚合物，这种液体不会蒸发或扩散，而是在表面形成一层薄薄的液体涂层，能够吸附和破坏病毒粒子。这些将与抗病毒纳米粒子结合，提供双重功能的材料。部署这些材料将通过限制感染机会来提高安全性，并将使我们的公共空间更安全、更快捷。

SARS-CoV-2 will remain a risk to Canadians as they return to work. Although testing, isolation, treatment, and contact tracing are essential, we also want to minimize the risk of virus transfer between people via touching a common surface. This project, led by the University of Windsor and Ontario coatings company Tessonics, combines three different strategies to develop a persistent antiviral coating that can be applied to surfaces and that will destroy the virions on contact. It will be safe for human contact, non-tacky, and comfortable to the touch. It could be applied to door handles in public buildings (hospitals, police or fire departments, employment agencies) and essential retail (grocery stores, pharmacies, gas stations), handles on gas pumps, keypads on payment systems, elevator buttons, electrical switches and other surfaces that are awkward to disinfect constantly and are touched by a large number of people. This is especially useful in public shared spaces such as airports and at large utility companies. We aim to use ultra-high boiling point liquids, or polymers based on them, that will not evaporate or spread, but will form a thin liquid coating on a surface able to adsorb and destroy virions. These will be coupled with antiviral nanoparticles to provide dual-functional material. Deploying these materials will increase safety by limiting opportunities for infection and will render our public spaces safer, faster.
