The Project applies quantum sensing to photonic measurements of a ring resonator containing a phase-shifted fibre Bragg grating.

The ground transportation industry has experienced a steep decline in traffic as a result of the COVID-19 pandemic. Canadians feel less safe travelling in mass transportation environments given the uncertainty surrounding the risk of contracting COVID-19 and future viruses in these spaces. The NRC and TC seeks to challenge the Canadian industry to develop solutions that can be used in existing federal, provincial, and municipal buses and trains to protect onboard occupants by mitigating the airborne viral risks while restoring confidence in transportation. 

Ventilation is an important layer of protection against COVID-19 transmission in indoor environments. However, many Canadian buildings lack a mechanical ventilation system that can provide outdoor air and/or air cleaning. Examples of these buildings include schools, long term care homes, and heritage buildings. As a result, there has been an emergence of building technologies and products aimed at mitigating airborne transmission of COVID-19 in buildings lacking a mechanical ventilation system. Unfortunately, many of the technologies and products that have emerged throughout the course of the COVID-19 pandemic lack experimental and field-validation to show they can effectively mitigate airborne transmission of respiratory viruses. In addition, some technologies contain various design flaws that can be detrimental to the health and safety of occupants, making them infeasible solutions. For example, many solutions are too difficult to install/position, too difficult to maintain, too expensive, too energy intensive, not designed optimally in terms of their air intake and exhaust, or result in other unintended negative health consequences (such as the generation of ozone and other contaminants, or produce disruptive levels of noise).
There is a need in the commercial marketplace for alternative building technologies and products that can safely and effectively mitigate airborne transmission of respiratory viruses in buildings lacking a mechanical ventilation system. The proposed solution should be capable of ensuring delivery of clean air to occupied zones both during and after occupancy while maintaining the accessibility and usability of the space.

There are numerous biomarkers present at low concentrations whose detection can provide valuable information pertaining an individual's health. Examples include but are not limited to; (i) antigens derived from SARS-CoV-2 whose presence in asymptomatic individuals is indicative of exposure or infection, (ii) cardiac troponin which when elevated is indicative of cardiac risk, (iii) various cytokine markers related to the "cytokine storm" seen in COVID-19 patients.
NRC is seeking innovations which can be used in diverse settings by minimally trained users to assess a human sample for the presence or quantity of one or multiple biomarkers, using a single device (i.e. multiplex detection) as to provide information to inform a subsequent course of action. The course of action may be that an individual seeks specific medical care, or following a proactive screening for an infectious disease and not needing to modify their behavior, or that they are suspected to have been exposed to an infectious organism and that they need to seek further testing or care.
While there are marketed products which can detect low concentrations of the aforementioned as well as other biomarkers, those products are confined to laboratories. The current COVID-19 pandemic has illustrated that there is significant need for an innovation which would allow individuals, or health care teams to test samples obtained via non-invasive means for the presence of one or multiple biomarkers present at low concentrations outside of traditional settings. The ability to detect and or quantify such biomarkers at low concentrations in nontraditional setting could prevent inadvertent spread of disease, or remote evaluation of individuals thus decreasing the burden on health care systems. Unfortunately, we do not currently have appropriate innovations.

As of June 29, 2020, based on federal government projections for PPE demand over the next year, it is estimated that approximately 63,000 tonnes of COVID-19 related PPE will end up as waste, being ultimately landfilled.
