The active biocidal agent in bioarmor-nano® coating is nanosilver and after recent test results were analysed it has been proven that “Nanosilver has been confirmed to be over 90% effective in reducing viruses when in a textile coating”. In light of these results we have stepped up our own testing of the nanosilver in our nano-coating to see if we can replicate/approximate those efficacy results within the framework of our coating.
Although we are quietly confident - we cannot claim viral efficacy (in addition to our certified antibacterial efficacy) until we have completed our testing (to ISO standard) on the bioarmor-nano product but these tests are ongoing and we will announce test results on this site as soon as we receive them.
An extract our lab's official website:
“the chemical building blocks of viruses are not invulnerable because they contain sulphur atoms. The sulphur atoms react with silver at the chemical level and lead to the irreversible destruction of the viral building blocks. Viruses are immobile: once placed on a surface, such as a door handle, they must first come into contact with silver. And this is where nano-technology brings its invaluable advantage; Silver can be used in the smallest quantities, finely divided and actively against viruses on surfaces such as door handles, handles, touch screens, etc. The effectiveness of nanosilver against viruses has been proven in numerous scientific studies that have been carried out worldwide (Source 1-7).
The project was to investigate the contribution to hygiene made by surfaces that are equipped with nanosilver. A double-blind study showed that the hygiene benefits are significant: 50% fewer germs settle on surfaces that contain nanosilver in the form of an ultra-thin coating than on surfaces that do not contain nanosilver (source 8). As a result, the project delivered a ready-to-use coating. The active ingredient nanosilver contained therein is marketable both in the EU and in the USA.
Our laboratory has increased it’s testing on viral efficacy on ‘nanosilver in bioarmor-nano coating’ since the beginning of this recent outbreak. We are testing to ISO 21702 standard which takes a set amount of time - but we will release more news on the efficacy results of nanosilver in the bioarmor-nano product against specific viruses at the end of April/beginning of May 2020.

Bioarmor-nano® active ingredient technology is currently tested to be effective on microbes and viruses 24/7 for the lifetime of the coating - which is a minimum of 3 months on a surface with normal usage.
The most important advice at this time is to follow the official government hygiene guidance and keep safe
We will update this section as soon as we receive updates and developments from the Lab.
Did you know that dust in our homes contains an average of 9,000 different species of microbes? That your phone screen has more nasty bacteria than a toilet seat? Research by the Good Housekeeping Institute also found that everyday electronic devices (like our phones, laptops and tablets) as well as handbags, remote controls, car sat-navs and the kitchen sink are hotspots for bacteria and microbes. Despite being regularly wiped-down, untreated kitchen worktops can contain an average of 1,736 bacteria per square inch. Meanwhile, bathroom taps and handles contain 50,068 and mobile phones 11,020. Pretty gross, right?
Bacterial and microbial growth can contribute to mould, surface degradation & nasty odours in the home.
