Developing a Face Mask that Kills COVID-19 on Contact
I have been working in nanotechnology for nearly two decades now, everything from cancer therapies to iron-enriched potatoes. When the pandemic first hit, we started making hand sanitizer for the NHS, care homes, and local businesses, but all the time I was thinking about what other ways we could make a difference.To get more news about famous mask wholesale, you can visit tnkme.com official website.
Then, Innovate UK opened a funding call, for scientists like me to prime some research that may make a difference. That then enabled me and the team at Pharm2Farm to test the antiviral properties of our nanomaterials, and then quickly move the technology forward to incorporate it into an antiviral face mask.
The funds from Remote Monitored Systems plc (the company behind Pharm2Farm) then funded all the equipment I needed to make 5 million masks a month. The only problem we have now is the UK alone, the demand for PPE facemasks is about 2 million a day!”The masks adopt the same barrier technology that is incorporated into a fluid-resistant Type IIR surgical mask; however, we have incorporated two of these layers rather than just one. The result is that the mask has a bacterial filtration efficiency (BFE) of 99.98%.
However, the problem with just having a filter is that you can end up trapping any nasty pathogens, like SARS-CoV-2, in the mask. If the filter then gets compromised (i.e. breaks) you could end up inhaling or exhaling a large concentration of the very thing you are trying to stop.
So, by adding an antiviral layer to the mask, we added an active mechanism for killing the viruses not just stopping it. Trap it, Kill it, Bin it!All the disposable 3-ply mask that are commonly available are not readily biodegradable, we are currently testing recyclable and compostable materials for a future generation of masks.
Our biggest limitation now is trying to scale up so that everyone around the world can have access to this anti-viral technology. We deliberately targeted the disposable surgical type masks as they have a price point that is accessible by everyone, however, they are not a tight-fitting mask like the more expensive KN95 “duckbill” models.
The next phase for us is to form strategic partnerships with some of these other face mask manufacturers and offer them our antiviral layer so that they can adapt it into their products too. Only together will we reach the demand.
