It seems to be a great product. If they get some company to properly market it in the region sure they can make some money. Publish the test results and start marketing...
The concept isn't new... It;s known for decades that nanoparticles can be used to kill bacteria & viruses. It was the Israeli company Sonovia, who first marketed it with their masks early last year. Then the Italians followed, they had the technology developed on their own and they also marketed a mask.
Several countries use the technology in disinfectants. Notably the Hong Kong University developed nanocapsule spray that lasts for 90 days on surfaces was marketed around $10.00 to $20.00 depending on size. It was sold under the name of Germagic.
The Australians developed"Nanoworm" water based polymer which does a similar job. If you search you will find others too.
Trying to sell a product without advertising is similar to winking at a girl in the dark.... You now what you are doing but nobody else does.
