CuSafeguard · Copper nanotechnology
Copper nanoparticles, bonded into every fibre
Our process atomically bonds copper ions to cellulose-based products such as fabrics and paper, using existing manufacturing techniques. The result is inherently viricidal and very rapidly deactivates the Covid-19 virus on contact.
The science
Permanent, not a coating
Ionic copper, alone or in copper complexes, has long been used as a disinfectant and biocide, on solid surfaces, in liquids and even on human tissue. Copper also has powerful antiviral properties, including against the coronavirus that causes COVID-19.
Our process creates copper nanoparticles that are irreversibly bound to cellulose fibres in situ: copper ions form permanent bridging atoms within the cellulose chains.
Evidence
Seen under the microscope
Optical microscopy of cotton before and after treatment: ropes of individual hair-like fibres, each about 50 µm across, become visibly copper-coloured.

In production
Three ways to use CuSafeguard
01
Drop-in functionalised pulp
We produce functionalised pulp in IBC quantities, used exactly like conventional pulp in your existing manufacturing lines.
02
Equipment on your site
Where supply chains are long or shipping costs too high, buy or hire functionalising equipment installed at your site.
03
Licensing
The technology is also available to license.
