The COVID-19 pandemic has led to a clear shortage in PPE supply. This has prompted many innovators to create various forms of reusable PPE solutions to resolve these issues. Despite this, there is still little technology that has been developed to examine the cleanliness of PPE while in use or after sanitisation.

As the Shield 9 Scanners team, we have developed a model using Raman hyperspectral images to detect pathogens on PPE surfaces. This technology is yet to be prototyped officially and tested. However, it has taken previous research as the basis of our proposal to use this method as a means to monitor the cleanliness of PPE through more scientifically in depth means.
