The study, entitled ‘Effective antiviral coatings for deactivating SARS-CoV-2 virus on N95 masks or filters’, published by Materials Today Advances, was a collaborative effort by ORNL, Iowa State University, RJ Lee Group, and Goldshield Technologies.
“We have successfully demonstrated the use of an antiviral coating (Goldshield 75 [GS75]) on masks and mask materials that is effective for deactivating both Alpha and Beta variants of the SARS-CoV-2. Goldshield will continuously inactivate the virus over a three-day period,” the researchers said in a press release.
The study also found GS75 did not degrade the material fibres and showed no toxicity. This success stems from the DOE Carbon Fibre Technology Facility who, explored avenues to integrate effective antiviral coatings that are safe for the wearer and the environment. ORNL’s long-term goal is to take these findings and apply them to other filters such as air filters for hospitals, or in combatting other pathogens.
“This landmark study confirms what over 70 independent scientific studies have shown Goldshield’s core chemistry not only inactivates COVID continuously for long-periods of time, but provides the best possible protection for frontline workers and the general public. The company plans to use this data to further their efforts with mask and air filter manufacturers as well as enhancing their VA, military, and commercial partnerships,” Goldshield CEO, Thomas Higgins, said in a statement.
Goldshield’s unique technology is the world's first water-stabilised antimicrobial formulation with a surface penetrating ingredient and effectiveness against microbes, including bacteria, mould, fungi and viruses, as demonstrated by ORNL. They will now seek additional regulatory filings and claims from the 24 Nations presently using Goldshield products.
