On Tuesday evening Andy was invited by James Whale to talk about the remarkable properties of our reusable face mask on his hugely popular ‘Evenings with James Whale’ Talk Radio show.

As a specialist coatings company, LiquidNano™ uses the most advanced nanotechnology available to deliver optimal coating protection for all kinds of surfaces.

For fabrics, DiOX® D4 is a powerful and invisible, anti microbial coating which uses a mechanical “kill” on pathogens such as Coronavirus.

We developed the facemask with this unique coating in response to the current pandemic and focused on efficacy, comfort, style and value.

It was also essential we created a reusable mask which would be much less impactful on the environment than disposable masks.

LiquidNano™ Di0X D4 Face Masks have been developed by an award-winning sportswear designer, with a unique toggle making it both stylish and comfortable to wear. 

At nanoscale DiOX® D4 uses a mechanical kill to ‘spike’ the lipid cell that surrounds the Coronavirus. It is made from nano scale quaternary ammonium salts (QUATS).  When the virus lands on the mask the lipid envelope is punctured with the ‘DiOX® spear’.

As all coronavirus variants have a lipid envelope, DiOX® D4 coated mask will provide protection for the wearer against all variants of Coronavirus.

Based on the test ISO18184/19 using SARS-COVID, conducted by Cambridge University’s Bio-Sciences department.

Dr Graham Christie at the Dept of Chemical Engineering & Biotechnology at Cambridge, said: “The antiviral agent within the coating of the mask kills the virus by breaching its protective outer membrane, which is known as its envelope. Unlike other parts of the virus, the membrane remains the same regardless of any type of mutation. Hence this way of attacking the pathogen will work on any new variant of coronavirus.

“In fact, you could mutate the entire genome of the virus and it would have no effect on the envelope. We expect to see the same response regardless of the strain of coronavirus because structurally they are all very similar”

The coating remains efficient for up to 20 washes which means washed once per week, one LiquidNano™ mask will last for 20 weeks. Using three disposable masks a day over the same period would mean 420 disposable masks ending up in landfill or our oceans.

As the coating also works well against other pathogens such as bacteria which cause odour, it is likely users may not need to wash the masks as often as once per week.

In effect, this remarkable, reusable and comfortable mask is self-sterilising.

“We followed the industry standard testing for viruses on material (ISO18184:19) but made some critical adaptations to give it a more ‘real-world’ relevance. This included conducting splash tests with the inoculum to mimic sneezing to ensure the tests were as rigorous as possible. We also used a mammalian Coronavirus as the inoculum, although we expect this material will be effective against many viruses, it is this class of virus that the world is obviously watching right now.’” Dr Graham Christie, Senior Lecturer in Bio Chemistry, Cambridge University
